Problems solved by technology

[0008] In view of this, Japanese Unexamined Patent Application Publication No. 2008-151316 Figure 4 and Image 6 It is shown that a plurality of hemispherical protrusions are provided on the outer surfaces of the guide plates, and these protrusions are in sliding contact with the standing wall portions of the chain guide or tensioner arm, so that when the guide plates and the A reduction in sliding friction is caused when the vertical wall parts come into sliding contact, but in such a case the guide plates need to undergo a separate pressing process in order to form the protrusions thereon, which complicates the production process

Abstract

[Issue] To allow deviation of a chain to be reliably restricted during travel, and also to allow friction loss to be easily reduced when the chain is operating. [Means of Resolution] A guide plate 4 is disposed on the outermost side in the width direction of a silent chain 1 comprising link plates 2 which are pivotably linked by means of linking pins 3. The guide plate 4 has a pair of pin holes 41 into which the linking pins 3 are inserted, and also has side end parts 42 which are disposed at both ends in the longitudinal direction thereof, and an upper end part 43 and a lower end part 44 which link the side end parts 42 in the longitudinal direction. The upper end part 43 and the lower end part 44 are formed with a tapered transverse section, and become steadily thinner toward the tip end.

Description

technical field [0001] The present invention relates to a guide plate placed on the outermost side of a chain, and to a chain equipped with such a guide plate; more precisely, the invention relates to an improved structure for reducing frictional losses in operation. [0002] [Fields of industrial application] [0003] The invention is suitable for chains with multiple guide plates, and it is particularly suitable when reduced frictional losses during operation are required. Background technique [0004] Silent chains are used as timing chains in vehicles such as motor vehicles and motorcycles. The silent chain generally has a configuration in which a large number of links each having a pair of tooth portions and pin holes are connected in a pivotable manner by a plurality of connecting pins which are inserted into each pin hole. to be connected, and a plurality of guide plates are arranged on the outermost side. [0005] In addition, a chain guide for guiding the chain t...
