Title:
TENSIONER
Document Type and Number:
WIPO Patent Application WO/2019/181690
Kind Code:
A1
Abstract:
This tensioner has: a tubular holding member; a movable member mounted to the holding member so as to be slidable in the axial direction; a thrust member mounted to the movable member so as to be relatively movable; a biasing member which is provided between the movable member and the thrust member, biases the thrust member outward in the axial direction of the holding member, and biases the movable member inward in the axial direction of the holding member; and a sliding force increasing means which is formed between and in contact with the movable member and the holding member, and which presses the movable member in a direction crossing the axial direction and thereby increases the sliding resistance between the thrust member and the holding member when the thrust member is moving.
