Abstract: Provided is a chain guide that offers improved assembly efficiency by a more easily engageable interlock structure, operates more quietly by reducing noise caused by collision between mating parts and looseness of the shoe, and improves durability by reducing wear and fatigue of the mating parts. A lateral interlock structure formed by hole parts 121 and mating protrusions 161 restricts relative displacement of the base 110 and the shoe 150. An opposite interlock structure formed by a groove part 131 and mating protrusions 171 restricts relative displacement of the base 110 and the shoe 150 in the height direction. The mating protrusions 161 and 171 are elastic mating elements. The lateral interlock structure and the opposite interlock structure are a snap-fit joint in which a meshed state is achieved through elastic deformation of the mating protrusions 161 and 171 that occurs in a moving process during assembly.
