Abstract:
Provided is a tensioner in which the number of parts is reduced to simplify the structure and which can be easily assembled. This tensioner is provided with: a first shaft member (3) affixed to a support member (2) in a non-rotatable state; a second shaft member (4) which is mounted to the first shaft member (3) while being engaged therewith by threads and which advances axially to directly or indirectly press a counterpart-member (340); and a spring (5) for applying rotational force to the second shaft member (4). The rotational force applied to the second shaft member (4) by the spring (5) rotates and advances the second shaft member (4) to press the counterpart-member (340).
