Fretting wear in a pipe connector is avoided in advance. In a connector body (), there is provided a gate member () having spring portions () that allow a pipe (P) to be inserted up to a regular depth while maintaining a contact state with the pipe (P). When a retainer () is pushed in with the pipe (P) being inserted to the connector body () up to the regular depth, locking legs () of the retainer () are locked to a bulge portion () of the pipe (P) and each locking leg () enters between the pipe (P) and the spring portion () and elastically displaces the spring portion () in a direction away from the pipe (P), thereby eliminating the contact state.

An intake system includes a supercharger for use with a power train. The power train includes a transverse engine and a transmission disposed transversely behind the engine. The engine has first and second rows of cylinders. Cylinders in each row are intended not to be fired one after another. The first and second rows of cylinders are offset sideways relative to each other. The intake system has an individual downstream intake part, downstream from the supercharger supported by the power train, for each row of cylinders. The individual downstream intake port includes a branch intake passage, branching off downstream from the supercharger and supported by the power train, and an inter-cooler disposed in the branch intake passage. One of the inter-coolers is located on a front side of the engine, and another of the inter-coolers is located above the transmission.

Plural auxiliaries are independently driven by a belt ot suppress an increase in the number of parts and simplify the structure. A cam shaft has first and second driving pulleys disposed in parallel to each other. A first auxiliary having a smaller load against the engine is movably mounted to the engine and it has a first following pulley mounted to its operating shaft which is coaxially and rotatably mounted with an idle pulley. On the other hand, a second auxiliary having a larger load against the engine is fixed to the engine. To the engine is movably mounted a tension pulley. A first belt for driving the first auxiliary is wound around the first following pulley, the first driving pulley and a tension pulley, while a second belt for driving the second auxiliary is wound around the second driving pulley and the idle pulley. The tension of the first belt is adjusted by transferring the tension pulley, while the tension of the second belt is adjusted by transferring the first auxiliary.
