Title:
AUTO-TENSIONER
Document Type and Number:
WIPO Patent Application WO/2017/195867
Kind Code:
A1
Abstract:
Engaging pieces (45, 46) that face tapered surfaces (16, 31) are formed into inclined shapes that incline inward, and the engaging pieces (45, 46) make use of recessed surfaces (47, 48) that come into contact with the corresponding tapered surfaces (16, 31) over a width in a circumferential direction, whereby, when engaging pieces of a fixing tool provided to an auto-tensioner hold a spring seat and a cylinder from both axial-direction sides, diameter-enlarging deformation of the engaging pieces in contact with the tapered surfaces of the cylinder or the spring seat is minimized and the fixing tool is prevented from separating.
