Abstract
A sprocket (A,B) is fixed onto a crank shaft () projecting outward from a cylinder block () of an internal combustion engine (). A timing chain (A,B) is looped around the sprocket (A,B). A slippage prevention mechanism () which prevents slippage of the timing chain (A,B) with respect to the sprocket (A,B) comprises an arm (C) extending from a base portion (A) fixed to the cylinder block. A slippage prevention rail (B) in the form of an arc-shaped recess is formed on the arm (C) so as to face the engaging part between the sprocket (A,B) and the timing chain (A,B) with a clearance smaller than the height of a tooth of the sprocket (A,B) therebetween. The slippage prevention rail (B) thus constructed does not interfere with other members fixed onto the crank shaft ().
