<p>A multistage transmission is provided that eliminates an axial space dedicated to biasing means for swingably biasing a swing claw member and that can use the swing claw members of the same kind in place of swing claw members of two kinds which establish engagement between a gear and a gear shaft and release the engagement in both relative rotation directions thereof. A multistage transmission that includes a swing claw member R having a pin--receiving member Rq adapted to receive a pin member and an engaging claw portion Rp on respective sides opposite to each other with respect to swing center, and swung by the advancement and retraction of the pin member to allow the engaging claw portion Rp to establish engagement and release the engagement; and biasing means for biasing the swing claw member R in a swing direction of bringing the engaging claw portion Rp into engagement. The biasing means is a compression spring interposed between the inner surface of the engaging claw portion Rp of the swing claw member R and the surface of the gear shaft opposed thereto.</p> |
