付性及び整備性を向上させることができる。 As described in detail above, according to the oil pipe mounting structure of the present invention, both ends of the oil pipe that connects the main body of an internal combustion engine and its peripheral parts, and through which oil flows to lubricate the sliding parts of the peripheral parts, can be connected. In the mounting structure of the oil pipe which is flanged to the respective mounting seats on the engine body side and peripheral parts side,
A plurality of male screw members are protruded from each of the mounting seats on the engine body side and the peripheral parts side, and a flange member having a plurality of through holes on at least one end side of the oil pipe is fitted so as to be freely movable in the axial direction, An annular bulge bulging outward in the radial direction is formed on the edge of the one end side of the oil pipe, and the corresponding male screw member is inserted into the through hole of the flange member to form the annular bulge. The oil pipe is sandwiched between a flange member and its corresponding mounting seat, and a female threaded member is screwed onto the corresponding male threaded member to tighten and fix the at least one end of the oil pipe to the corresponding mounting seat. By shifting the freely movable flange member to a position appropriately spaced from the annular bulge when assembling the oil pipe, interference with the male mounting member, which is screwed in advance, can be avoided, and the flange member can be transparent. The position of the oil pipe can be easily determined by simply inserting the male mounting member into the hole, and even if the relative position between the supercharger side mounting seat and the engine body side mounting seat is slightly shifted due to thermal expansion, it will not move. The freely movable flange member allows the oil pipe to be assembled by absorbing this relative positional deviation, thereby improving the ease of assembling and maintaining the oil pipe.
