The second hinge portion 320 includes an upper second hinge portion 321 and a lower second hinge portion 322, and is configured similarly to the first hinge portion 210. The upper second hinge portion 321 and the lower second hinge portion 322 are engaged with each other in a protrusion-recess manner, similar to the upper first hinge portion 211 and the lower first hinge portion 212. The third member 300 rotates around a rotation axis 323 of the second hinge portion 320. As such, the third member 300 is connected to the first member 100 through the second hinge portion 320.


The second member 200 and the third member 300 includes a second traveling wheel 250 and a third traveling wheel 350, respectively. The second traveling wheel 250 and the third traveling wheel 350 include wheels 251 and 351, that are rotatably provided on the second member 200 and the third member 300, respectively. Since the second traveling wheel 250 and the third traveling wheel 350 have the same structure, the structure of the traveling wheels will be explained using the third traveling wheel 350 as an example.


As illustrated in FIG. 4, the wheel 351 is provided with a wheel member 352 and a tire member 353 fixed to the wheel member 352. The wheel member 352 includes a shaft 352a protruding toward the inside (the side surface plate 301 side). An inner cylinder 353a is formed in the tire member 353. Meanwhile, a bearing 354 protrudes from the third member 300. The bearing 354 is provided with two supporting portions 354a with a predetermined interval therebetween to sandwich the shaft 352a. The inner cylinder 353a provided in the tire member 353 is disposed around the bearing 354. As such, in the third traveling wheel 350, the wheel 351, the wheel member 352, and the tire member 353 rotate integrally around the axis of the shaft 352a (rotation axis 355, see FIG. 3).


As illustrated in FIG. 3, the wheel 251 of the second traveling wheel 250 and the wheel 351 of the third traveling wheel 350 are rotatably provided around the rotation axes 255 and 355, respectively. The rotation axes 255 and 355 are coaxially disposed. Therefore, the traveling toy for figure play 10 is supported like three-point support by the first traveling wheel 110 that rotates integrally, and the second traveling wheel 250 and the third traveling wheel 350 that rotate independently, so that the traveling toy for figure play 10 can travel stably.


Since the second traveling wheel 250 and the third traveling wheel 350 are not connected, the second member 200 and the third member 300 can be opened in the left and right direction, respectively. Therefore, the user can enjoy playing with the changing vehicle body.


As illustrated in FIG. 5, at front ends of the bottom plate 203 of the second member 200 and the bottom plate 303 of the third member 300, surface-sliding portions 203a and 303a having convex arc-shaped tip edges are formed. The surface-sliding portion 203a serves as an example of a first surface-sliding portion, and the surface-sliding portion 303a serves as an example of a second surface-sliding portion. When the second member 200 and the third member 300 are closed, the surface-sliding portions 203a and 303a are disposed on the lower surface side of the bottom plate 101 of the first member 100 (see FIGS. 2 and 3). When the second member 200 and the third member 300 are closed, the upper surfaces of the bottom plates 101, 203, and 303 become substantially continuous surfaces.


As illustrated in FIGS. 3 and 5, the bottom plate 101 of the first member 100 is provided with surface-sliding receiving portions 101a and 101b. The surface-sliding receiving portion 101a serves as an example of a first surface-sliding receiving portion, and the surface-sliding receiving portion 101b serves as an example of a second surface-sliding receiving portion. The surface-sliding receiving portions 101a and 101b are disposed on the upper side facing the surface-sliding portions 203a and 303a when the second member 200 and the third member 300 are closed. On the front side of the surface-sliding receiving portions 101a and 101b, contacting wall portions 101a1 and 101b1 are formed which have a rib-shaped convex arc shape and come into contact with the surface-sliding portions 203a and 303a. The rear edges of the surface-sliding receiving portions 101a and 101b are formed in a convex arc shape, similar to the tip edges of the surface-sliding portions 203a and 303a. The upper surfaces of the surface-sliding portions 203a and 303a and the lower surfaces of the surface-sliding receiving portions 101a and 101b come into sliding contact with each other during the opening and closing operation of the second member 200 and the third member 300 (opening and closing operation of the second member 200 or the third member 300 by the first hinge portion 210 or the second hinge portion 320).


The surface-sliding portions 203a and 303a and the surface-sliding receiving portions 101a, 101b have edges that substantially face each other in the horizontal direction (for example, closing directions of the second member 200 and the third member 300) and are formed in a convex arc shape. Therefore, even if a finger is inserted between the facing edges of the surface-sliding portions 203a and 303a and the surface-sliding receiving portions 101a and 101b, the finger is easily pushed out when the second member 200 and third member 300 are closed. The edge of the surface-sliding portion 203a and the edge of the surface-sliding receiving portion 101a serve as an example of first edges, and the edge of the surface-sliding portion 303a and the edge of the surface-sliding receiving portion 101b serve as an example of second edges.


A regulating portion 202a imitating a tail lamp is provided on the upper part of the rear surface plate 202 of the second member 200. The regulating portion 202a is provided to protrude beyond the edge of the rear surface plate 202. When the second member 200 and the third member 300 are closed by the regulating portion 202a, an outer surface of the rear surface plate 302 of the third member 300 is guided by the inner surface of the regulating portion 202a, and a positional deviation between the second member 200 and the third member 300 hardly occurs.


A lock member 305 is provided on the rear surface plate 302 of the third member 300 to be freely rotatable. The lock member 305 can lock the opening operation of the second member 200 and the third member 300 by engaging an engagement protrusion 205 provided on the rear surface plate 202 of the second member 200.


As illustrated in FIG. 5, inside the second member 200 and the third member 300, three independent toys for figure play 500 (independent toys for figure play 510, 520, and 530), which can be used for figure play independently, are stored separately from the traveling toy for figure play 10.


As illustrated in FIG. 6, by placing the independent toy for figure play 510 stored on the bottom plate 203 of a first floor part of the second member 200 on a desk or the like, in an opposite manner to a state in which the independent toy for figure play 510 is attached to the traveling toy for figure play 10, it is possible to play seesaw with the independent toy for figure play 510. The independent toy for figure play 510 includes a plurality of two seats 514 and a seesaw main body 501. The seesaw main body 501 is provided with two side plates 511 that are long in the front and rear direction and are provided facing each other.

A recess groove 511b is provided in a portion of the side plate 511 (the other side (a second surface side) of the seesaw main body 501) that opposes the bulging portion 511a, and engages an elongated protrusion 203b (see FIG. 5) provided on the bottom plate 203 of the second member 200 in a protrusion-recess manner to restrict movement of the seesaw main body 501. The independent toy for figure play 510 is stored in the second member 200 to be freely attachable thereto and detachable therefrom by the protrusion-recess engagement between the recess groove 511b and the elongated protrusion 203b.


A support plate 513 is provided between the two side plates 511 of the seesaw main body 501, with the plate surfaces thereof facing in the vertical direction. Two seats 514 including backrests are provided on the support plate 513 to be freely attached and detached. A figure used for figure play can be seated on the seat 514.


When the independent toy for figure play 510 is attached to the traveling toy for figure play 10 as illustrated in FIG. 5, the seat 514 is attached to one side of the support plate 513 with the bulging portion 511a of the side plate 511 facing upward. The seat 514 is fixed by fitting two protrusions 514a provided on the lower surface of the sheet 514 into through-hole portions 513a that are provided in the support plate 513 in pairs at two locations in the front and rear sides.


When removing the independent toy for figure play 510 from the traveling toy for figure play 10 and playing with the independent toy for figure play 510 independently, the seat 514 is removed from the seesaw main body 501, and the seat 514 is attached to the other side of the support plate 513 of the seesaw main body 501 with the bulging portion 511a placed on a desk or the like. That is, the seat 514 is attached to the support plate 513 on the opposite side from when the independent toy for figure play 510 is attached to the traveling toy for figure play 10.


In attaching the seat 514 to the support plate 513, the seats 514 can be attached to the support plate 513 so that both two seats face toward the front side when the independent toy for figure play 510 is attached to the traveling toy for figure play 10, and the seats 514 can be attached to the support plate 513 so that the seats 514 face each other when playing seesaw with the independent toy for figure play 510.


The seesaw main body 501 is provided with tongue piece-shaped locking portions 513b that are respectively provided at both side ends of the support plate 513. With the second member 200 and third member 300 open, the seesaw body 501 can also be played as a slide by being engaged to the second floor plate 230 of the second member 200 with the other side of the support plate 513 facing upward to be sandwiched between one locking portion 513b and an end portion of the support plate 513 and installing an end of the support plate 513 on the other locking portion 513b side on a desk or the like.


As illustrated in FIG. 5, in the second floor portion of the second member 200, an independent toy for figure play 520 is attached to the second floor plate 230 to be freely attached and detached. The independent toy for figure play 520 includes a rotating body 521 including four four-leaf clover-shaped seats, and a shaft portion 522 provided at the center of the rotating body 521 as a rotating shaft. The shaft portion 522 is provided with a disk-shaped installation portion 522a provided at the lower end, and a locking disk portion (not illustrated) provided on the upper side of the installation portion 522a.
