<P>PROBLEM TO BE SOLVED: To provide a layout structure for an accessory belt capable of suppressing the surface pressure of a crankshaft and that of a crank bearing. Ž<P>SOLUTION: The layout structure includes a crank pulley 12, an auto-tensioner pulley 14, a plurality of the accessory belts 16, 18, 20, and the endless accessory belt 22 transmitting the torque of the crank pulley 12 to each pulley 14, 16, 18, 20. The crank pulley 12 and a crank sprocket 28 of a chain tensioner 26 are fixed to the crankshaft 24. The structure is applied in an accessory drive device 10, and the accessory belt 22 is wound so as to meander between the crank pulley 12 and each pulley 14, 16, 18, 20 so that a direction of a pressing load vector 34A to the crank pulley 12 is in an opposite direction to a direction of a chain load vector 34B of the chain tensioner 26.
