A tensioner is provided with a movable member, a stationary member, a pressing means which is disposed between the stationary member and the movable member and which presses the movable member in the pressing direction, and a damping member which is disposed between the stationary member and the movable member and damping the pivoting of the movable member. The damping member consists of a resin composition which damps the pivoting of the movable member by a sliding frictional force, and the contact angle of the resin composition with water is in the range of 70� to 100� inclusive. |
