Abstract
An apparatus for transmitting power by a chain engaged with sprockets incorporates therein with a chain retaining member at a position at which the chain engages with one of the sprockets for maintaining the engagement between the chain and the one sprocket. With the provision of the chain retaining member, even if the chain becomes loose due to elongation with age, disengagement of the chain from the sprockets can be eliminated, resulting in a reduction in the frequency at which the chain tension must be adjusted.
