CHAIN GUIDE AND CHAIN TRANSMISSION DEVICE

Japanese Patent JP2015102232

A

PROBLEM TO BE SOLVED: To suppress the deflection of a guide base, and to reduce vibration and noise, in a change guide which guides the movement of a chain.SOLUTION: One end of a curved guide base 20 which is arranged along a moving direction of a change 5, and to which a plurality of rotatable roller bearings 40 are oriented at intervals in its longitudinal direction is supported by a pivot shaft 10 so as to be oscillatory. An adjustment force of a change tensioner 11 is loaded to an oscillation-side end part of the guide base 20, and the chain 5 is pressed against a plurality of the roller bearings 40, and rollingly guides the bearings. A pivot shaft 10 being an oscillation center of the guide base 20 is located at a position which is shifted to a center part of the guide base 20 in the longitudinal direction from the roller bearings 40 located at the other end part of an oscillation center side of the guide base 20, the roller bearings 40 are arranged outside the pivot shaft 10, the rotational moment loaded to the remaining roller] bearings 40 is reduced by the rotation moment which is loaded to the roller bearings 40 at an end part by push-pressing from the chain 5, and the deflection of the guide base 20 is suppressed.
