Moreover, a configuration shown in
A lever mounting portion 400 for mounting a lever operated by an operator located on a top surface of an exterior cover 700 forming an outer shell of a console box 110. Console pockets 500 for storing small items and so on is located at a rear of the lever mounting portion 400 (in a negative direction of a Z axis).
Each of the console pockets 500 has a hook 501 to each of a front end (a positive direction of the Z axis) and a rear end (refer to
In the console box 110 having the above configuration, once the console pockets 500 are accommodated in the exterior cover 700 and fixed, a curved shape of the hooks 501 engages with the locking member 701, thereby making it difficult to move the console pockets 500 upwardly. In other words, the console pocket 500 cannot be easily removed from the exterior cover 700, and if the console pocket 500 is to be removed, the exterior cover 700 needs to be disassembled and removed.
On the other hand, in the construction machine to work at construction sites, since sand and dust are likely to be accumulated inside the console pockets 500 more than the general passenger cars, there is a need to frequently clean the inside of the pockets. If there is a need to disassemble the exterior cover 700 in order to remove the console pockets 500, the inside of the pockets is resultantly wiped and cleaned with the use of a hand towel or the like in consideration of the time and effort. On the other hand, if the console pockets 500 are removed and the console pockets 500 themselves are washed with water, cleaning can be performed efficiently, and a state after cleaning also becomes excellent.
In addition, the construction machines working at the construction sites and the like have many opportunities to travel on a bad road surface, and are affected by machine operations involved in a site work, so that the construction machines suffer from a greater amount of shock and vibration than general passenger cars. Therefore, there is a need to attach the console pockets 500 to the exterior cover 700 with a certain degree of rigidity so as to have a resistance to shock and vibration. Since the accommodation device disclosed in Patent Literature 1 described above is mainly intended for the general passenger cars, an ashtray member or the like corresponding to the console pocket is simply fitted into the storage portion, and a configuration for firmly attaching is not provided.
The present invention has been made in view of the above problem, and an object of the present invention is to provide a console box in which a unit such as a console pocket is firmly and easily detachably attached to a cover.
