Abstract
Provided is a chain guide that enables a reduction in size with a simple structure, without lowering the strength of the chain guide. The base member 30 includes a side wall rib 32 or 33 extending upward higher than a shoe support surface 31 at at least one of both side edges 31a and 31b in a guide width direction. The guide shoe 20 includes, at at least one of both side edges 20a and 20b in the guide width direction, an upstream lip 22, a downstream lip 23, and a shoe widthwise recess 24 formed between the upstream lip 22 and the downstream lip 23 by inwardly recessing the side edge 20a or 20b of the guide shoe 20 in the guide width direction. The side wall rib 32 or 33 is located inside the shoe widthwise recess 24.
Claims4
A chain guide comprising:
- a guide shoe having a shoe surface that slidably guides a running chain;
- and
- a base member having a shoe support surface that supports the guide shoe,
- the base member including a side wall rib extending upward higher than the shoe support surface at at least one of both side edges in a guide width direction of the base member,
- the guide shoe including, at at least one of both side edges in the guide width direction thereof, an upstream lip, a downstream lip spaced apart in a guide longitudinal direction from the upstream lip, and a shoe widthwise recess formed between the upstream lip and the downstream lip by inwardly recessing a side edge of the guide shoe in the guide width direction, and
- the side wall rib being located inside the shoe widthwise recess.
