Abstract
A saw chain tensioning mechanism for adjusting the tension in a saw chain extending around a chain guide plate includes a threaded rod member disposed adjacent to a rear end of the chain guide plate and along the longitudinal direction of the chain guide plate, a movable member engaged with the chain guide plate and adapted to be moved along the threaded rod member by a rotation of the threaded rod member, and a driving gear integral with the threaded rod member. The tensioning mechanism includes a driving gear for rotatively driving the driving gear and an operating member for manually rotating the driving gear. Manipulating the operating member changes the longitudinal position of the chain guide plate and correspondingly causes a change in a tension of the saw chain.
