An object of the present invention is to provide a chain drive system that can reduce sliding resistance between a chain and a guide shoe, minimize increase of sliding resistance over time, and reduce production cost. Provided is a chain drive systemincluding a plurality of sprocketsandover which a chainpasses over, and one or more guidesandthat guide the chain. The guidesandinclude integral or separate guide shoesandeach having a chain running surface. The chain running surfaces include, in part thereof, a lubricated areawhere a solid lubricant P is held.

Chain drive system

A chain guide is provided that allows for stable running of a chain, causes less wear or damage on the inner surface of mounting holes or on mounting shafts, and improves the durability without increasing production cost. The guide shoe includes a guide rail and a unit holding part that accommodates a reinforcing unit inserted thereinto from the backside of the guide rail. The reinforcing unit includes a plate and a spacer. The plate and spacer are aligned in a guide width direction, so that a plate through hole and a spacer through hole are continuous in the guide width direction, and are disposed in the unit holding part

Chain guide

To provide a chain guide that implements stable running of a chain, causes less wear or damage on the inner surface of mounting holes or on mounting shafts, and improves the durability of a reinforcing plate thereof without increasing production cost. A guide shoe includes a guide rail and a plate holding part accommodating a reinforcing plate inserted thereinto from the backside of the guide rail. The reinforcing plate includes a tubular part integral with a first plate surface and protruding from the edge of a mounting hole that extends through the reinforcing plate in a guide width direction. In the chain guide, a plurality of surface irregular parts are provided on a peripheral outer side of the tubular part in stripes along a plurality of imaginary circles concentric to the tubular part on at least one of the first plate surface and a second plate surface.
