Abstract

PURPOSE: To prevent the generation of vibration and noise by providing on a projected elastic member a buffer intervening in a sprocket in order to eliminate the clearance beween a bush of a chain and a roller when the chain is engaged with the sprocket.
CONSTITUTION: A pin 13 projecting at its top and a spring 12 are inserted into an insert hole 11 of a buffer 10. Now, before a chain 6 is engaged with a sprocket 5, a clearance (c) is formed between a roller 3 and a bush 4. But, when the chain 6 approaches the sprocket 5, the roller 3 is brought into contact with the top of the pin 13, and then the bush 4 comes in contact with the roller 3 for reducing the clearance (c) to zero. At this stage, the pin 13 is retreated to the side of the sprocket 5 to absorb the impact of the bush 4, while the spring 12 is contracted, consequently impact sound and vibration are hardly generated.
