Abstract
A tensioner guide includes a stationary shoe (6) having a contact surface (6A) confronting a free span of a transmission chain (4) between a pair of sprockets (2, 3), a movable shoe (7) movable relatively to the stationary shoe (6) in a direction toward and away from the transmission chain free span, and an urging member (9) for urging the movable shoe (7) toward the transmission chain free span. The movable shoe (7) has a contact surface (7A) being pressed against and in slide contact with the transmission chain free span by the action of the urging member (9) to hold a tension in the transmission chain (4). The movable shoe (7) is movable, in response to a decrease in the tension in the transmission chain (4), to project from the contact surface (6A) of the stationary shoe (6) to take out slack in the transmission chain (4) and, in response to an increase in the tension in the transmission chain (4), to retract into the contact surface (6A) of the stationary shoe (6) to such an extent that the contact surface (6A) of the stationary shoe (6) and the contact surface (7A) of the movable shoe (7) are both in sliding contact with the transmission chain free span.
