Title:
CHAIN GUIDE AND CHAIN TENSIONER DEVICE
Document Type and Number:
WIPO Patent Application WO/2012/114959
Kind Code:
A1
Abstract:
Provided are: a chain guide that provides good assembly work efficiency, has high strength and little sliding resistance in a surface that comes in contact with a chain, is resistant to abrasion even if the chain traveling at high speed comes in contact therewith, and has low noise and little vibration; and a chain tensioner device using same. A roller (12) that comes in contact with the chain (1) is configured by: a support shaft (13) supported by opposing guide bases (9) disposed along the travel direction of the chain (1); and a roller bearing disposed on the outer peripheral surface of the support shaft (13) and having a steel outer ring (12a) that comes in contact with the chain (1). Both ends of the support shaft (13) are configured to be assembled by inserting same into support recesses (14) provided in the opposing wall surfaces of the guide bases (9). The roller (12) that comes in contact with the chain is configured to be unlikely to transmit vibration from the support shaft (13) to side plate members (9), by the housing of a vibration-damping material (17) between the support shaft (13) supported by the opposing side plate members (9) disposed along the travel direction of the chain (1) and the support recesses (14) for the side plate members (9) which support both ends of the support shaft (13).
