Patent ID: 8555739

Claim:
A shift control device of a saddle-ride-type vehicle having an engine and a transmission, wherein the transmission includes a shift spindle which is rotated due to an external force for shifting, and a shift drum which is intermittently rotated corresponding to the rotation of the shift spindle, so as to operate a shift fork and thereby performing the selection of a shift gear, said shift control device comprising: a lost motion mechanism disposed between the shift spindle and the shift drum, and which engages an upstream-side rotary member on a shift spindle side thereof, and a downstream-side rotary member on a shift drum side thereof, in a relatively rotatable manner while accumulating a force, and a locking mechanism engaged with said upstream-side rotary member and said downstream-side rotary member, respectively, so as to restrict the rotation of said upstream-side rotary member and the rotation of said downstream-side rotary member individually.
