In a throttle body, a cylindrical body member is made of resin, and a core is made of a material different from the body member and insert molded in the body member. A notch is provided on an outer surface of the body in a peripheral direction, in a proximity of the core. The body member is readily split at the notch when external force is applied to the body member during a dismantling. Therefore, the core is readily removed from the body member. Alternatively, the body member can be constructed of a first body having a hook and a second body having a hook-receiving portion. Both the first and second bodies are connected to each other through the hook and the hook-receiving portion, and the core is held between both the first and second bodies. Thus, the core is readily removed from the body by unhooking the hook.
