Chain tension device in a chain saw |
摘要 |
A chain tension device for tensioning a cutting chain of a chain saw utilizing a guide bar having an outer periphery and a drive sprocket. The chain saw body supports the guide bar, the sprocket and a drive source. A cutting chain is wound around the sprocket and the outer periphery of the guide bar and a leaf spring is supported by the chain saw body and interposed between the guide bar and the sprocket. The leaf spring abuts and biases the guide bar away from the sprocket so as to apply automatically an appropriate amount of tension to the cutting chain.
