<p>A blade tensioner (1) includes a blade shoe (2) with a chain sliding face (2a) bending in an arch-like shape and a blade spring (3), arranged on a side opposite to the chain sliding face (2a) of the blade shoe (2), that applies spring force to a chain through the blade shoe (2). The tensioner (1) also includes a bracket (4) with a pin (41) rotatably supporting a proximal end section of the blade shoe (2) and a sliding section (5) made of resin slidably supporting an end of the blade spring (3) on the distal end section of the blade shoe (2) when the blade shoe (2) is deformed. The distal end section of the blade shoe (2) preferably includes a pair of guide sections (22A,22B) vertically provided along both surfaces of a sliding section (5) of the bracket (4).</p> |
