Abstract
To reduce the engaging sound to a low level, generated at the time of changing over the change gear stage by sliding a shifter, an intermittent feed mechanism includes a drum shifter, a pair of pawls symmetrically mounted to the drum shifter and energized in tilting-up directions, engaging recesses provided at regular intervals along the circumferential direction at the inner periphery of a shift drum center so as to be capable of engagement with both the pawls, and a fixed guide plate for guiding the tilted conditions of both the pawls. The guide plate is provided with a large-diameter arcuate part, a small-diameter arcuate part, and connecting parts. The pawls are engaged with the engaging recesses by the connecting parts, in the course of turning of the drum shifter by a turning amount necessary for changing over the establishment conditions of a plurality of change gear stages of gear trains.
