Claims
- 1. A fishing reel, comprising:
- a reel body (1) having an interior side plate (1A);
- a feed shaft (5) for axially reciprocating a level wind mechanism (4), said feed shaft being rotatably supported by said side plate, said feed shaft having a diameter; and
- torque transmitting structure for transmitting torque to said feed shaft, said torque transmitting structure comprising:
- a torque transmitting gear (8) which is coaxial with said feed shaft, said torque transmitting gear having a first face that faces toward said side plate and a second face that faces away from said side plate, said fishing reel being arranged such that the distance between said first face and said side plate is no greater than a gap width (l);
- a joint shaft (9) extending from an end surface of said feed shaft facing said gear, said joint shaft being coaxial with said feed shaft, said joint shaft having a diameter, the diameter of said joint shaft being less than the diameter of said feed shaft;
- an engaging head (10) projecting from an end of said joint shaft, said engaging head being in the shape of a bar with a substantially square cross-section, said engaging head having a thin rectangular engaging face which is perpendicular to the axis of said feed shaft and which faces said end surface of said feed shaft, said engaging face having two elongated edges, and said engaging head having two thin rectangular torque transmitting faces extending from said elongated edges of said engaging face, said torque transmitting faces being parallel to each other;
- a radially extending slot (14) for allowing said engaging head to move through said gear, said slot being located at the center of said gear; and
- a retaining means (11) which is matable with said engaging head, said retaining means being angularly displaced with respect to said slot, said retaining means being located on said second face of said torque transmitting gear, said retaining means having a bottom engaging wall (13) for engaging said engaging face of said engaging head, said retaining means also having side surfaces (12) for contacting and transmitting torque to said torque transmitting faces, said side surfaces being perpendicular to said bottom engaging wall, said side surfaces (12) having an axial width (L) in a direction parallel to the axis of said feed shaft, said axial width (L) being greater than said gap width (l).
- 2. A structure for transmitting torque to a feed shaft (5) of a fishing reel, comprising:
- a torque transmitting gear (8) which is coaxial with said feed shaft;
- a joint shaft (9) extending from an end surface of said feed shaft facing said gear, said joint shaft being coaxial with said feed shaft;
- an engaging head (10) projecting from an end of said joint shaft, said engaging head being in the shape of a bar with a substantially square cross-section, said engaging head having a thin rectangular engaging face which is perpendicular to the axis of said feed shaft and which faces said end surface of said feed shaft, said engaging face having two elongated edges, and said engaging head having two thin rectangular torque transmitting faces extending from said elongated edges of said engaging face, said torque transmitting faces being parallel to each other;
- a radially extending slot (14) for allowing said engaging head to move through said gear, said slot being located at the center of said gear; and
- a retaining means (11) which is matable with said engaging head, said retaining means being angularly displaced with respect to said slot, said retaining means being located on a face of said gear that faces away from said feed shaft, said retaining means having a bottom engaging wall (13) for engaging said engaging face of said engaging head, said retaining means also having side surfaces (12) for contacting and transmitting torque to said torque transmitting faces, said side surfaces being perpendicular to said bottom engaging wall; and
- wherein said side surfaces are formed by projections (17) which project axially from said face of said gear.
- 3. A structure for transmitting torque to a feed shaft (5) of a fishing reel, comprising:
- a torque transmitting gear (8) which is coaxial with said feed shaft;
- a joint shaft (9) extending from an end surface of said feed shaft facing said gear, said joint shaft being coaxial with said feed shaft;
- an engaging head (10) projecting from an end of said joint shaft, said engaging head being in the shape of a bar with a substantially square cross-section, said engaging head having a thin rectangular engaging face which is perpendicular to the axis of said feed shaft and which faces said end surface of said feed shaft, said engaging face having two elongated edges, and said engaging head having two thin rectangular torque transmitting faces extending from said elongated edges of said engaging face, said torque transmitting faces being parallel to each other;
- a radially extending slot (14) for allowing said engaging head to move through said gear, said slot being located at the center of said gear; and
- a retaining means (11) which is matable with said engaging head, said retaining means being angularly displaced with respect to said slot, said retaining means being located on a face of said gear that faces away from said feed shaft, said retaining means having a bottom engaging wall (13) for engaging said engaging face of said engaging head, said retaining means also having side surfaces (12) for contacting and transmitting torque to said torque transmitting faces, said side surfaces being perpendicular to said bottom engaging wall; and
- wherein said joint shaft is rotatably supported on a boss (24) fixed to said reel body, and
- wherein a bush (25) is maintained between said boss and said gear, whereby said gear is secured to said feed shaft.
- 4. A structure for transmitting torque to a feed shaft of a fishing reel as set forth in claim 3, wherein said bush has a through hole (25a) for receiving said engaging head.
