Abstract

A tensioner adapted so that a second shaft member is stably propelled. An inner first shaft member (3) and an outer second shaft member (4), which are connected by screw sections (8, 10), and an urging spring (5) for urging the first shaft member (3) in one direction are received in a case (2). Rotation of the second shaft member (4) is restrained, and rotational urging force of the urging spring (5) is converted into propelling force of the second shaft member (4). The first shaft member (3) is rotated with its shaft end portion directly or indirectly in contact with the case (2). A friction member (6) for generating frictional force between itself and the first shaft member (3) is provided so as to be directly or indirectly in contact with the first shaft member (3). An elastic member (7) is provided on the radially outer side of the second shaft member (4). The elastic member (7) urges the friction member (6) in the direction in which it is in contact with the first shaft member (3), and this stabilizes propelling of the second shaft member (4).
