Abstract: The present invention is capable of suppressing gear shift shocks or delays in acceleration with no interruption of driving force and reducing the weight. Disclosed is a transmission which is provided with multiple stage shift gears so arranged to shift a number of dog clutches to shift a gear to the upper stage of the multiple stage shift gears, and is characterized in that a guide part is provided to a shift operation section and the dog clutches on each of the sages so as to move the lower dog clutch in a neutral direction by a coasting torque acting on the lower stage by a shift rotation of the upper stage to release a meshing engagement when meshing engagements of the lower and upper dog clutches are simultaneously performed by an operation of the shift operation section.

Abstract: A sleeve in the shift control device includes a sleeve main body and a first convex section. The first convex section is annular in shape and protruded radially outward from the outer circumferential surface of the sleeve main body. The shift fork includes a fork main body, a second convex section, a ring, and a joining member. The fork main body is annular in shape and disposed radially outside the sleeve main body. The second convex section is annular in shape, axially disposed side by side with the first convex section, and protruded radially inward from the inner circumferential surface of the fork main body. The first convex section is axially sandwiched between the ring and the second convex section. The joining member is disposed in a space that is formed by a first groove formed in the ring and a second groove formed in the fork main body.
