Title:
オートテンショナ
Document Type and Number:
Japanese Patent JP6659454
Kind Code:
B2
Abstract:
A fixing tool of an auto-tensioner includes inwardly inclined engaging pieces (45 and 46) to be opposed to respective tapered surfaces (16 and 31) of a spring seat and a cylinder of the auto-tensioner. The engaging pieces (45 and 46) have concave surfaces (47 and 48) that contact the tapered surfaces (16 and 31) over a circumferentially extending area. This minimizes the deformation of the engaging pieces such that the diametrical distances therebetween increase due to contact with the tapered surfaces when sandwiching the spring seat and the cylinder with the engaging pieces from the axially opposite directions, thereby preventing the fixing tool from coming off.
