Title:
SADDLE RIDE TYPE VEHICLE
Document Type and Number:
Japanese Patent JP2007113653
Kind Code:
A
Abstract:

To prevent the occurrence of idle rotation of a rear wheel occurring due to sticking of a clutch plate and a friction plate of a centrifugal clutch in a saddle ride type vehicle.

A helical gear 80b on the left side half of a gear 80 rotating interlockingly with a clutch boss 77 of the centrifugal clutch 44 in a motorcycle is meshed with a first shift shaft 103 which is a helical gear for transmitting driving force to a shift shaft 100. Frictional force generates to the gear 80 by a washer 143 being pressed by an energizing force of a disk spring 140, and the frictional force becomes a braking force of the rear wheel 26. The helical gear 80b is provided so that the thrusting force working by receiving the driving force works in a reverse direction from the energizing force of the disk spring 140.
