ABSTRACT:
A tensioner device for a power transmission chain, which has a small number of components and hence is able to reduce the cost of manufacture and assembly, can be mounted or installed easily, and requires only a small space for installation thereof. The tensioner device consists of a tensioner lever (4) pivoted at one end thereof on a support shaft (3) disposed on a fixed member (2) and carries, on a surface thereof facing a chain (7), a shoe (8) slidably engageable with the chain (7). The opposite end of the tensioner lever (4) has formed therein a plunger receiving hole (9) having an opening (9A) facing in a direction opposite to the surface to which the shoe (8) is attached. A plunger (10) is slidably received in the plunger receiving hole (9) and is held in abutment with a stopper (17) disposed on the fixed member (2). The plunger (10) is urged in a forward direction projecting outwardly from the plunger receiving hole (9), and a unidirectional restriction device resists movement of the plunger (10) in the reverse direction.
