Abstract
The present invention provides a timing chain drive device which has high mechanical strength of the timing chain contact surface and small sliding resistance, and which, even when being brought into contact with a timing chain running at high speed, is difficult to wear. A first chain guide and a second chain guide, which give tension to a timing chain so as to prevent the timing chain from being slackened, are arranged, and a plurality of rollers, each of which is supported by a rolling element, are arrayed in each of the first chain guide and the second chain guide so as to be brought into contact with the timing chain.
