<P>PROBLEM TO BE SOLVED: To fit a motor unit for hybrid vehicles by fastening screws in the same direction without changing the specifications of connection parts of an engine and a transmission. <P>SOLUTION: The motor unit 20 includes: a plurality of first through-holes 21c1 formed by penetrating a first connection part 21c; a plurality of second through-holes 21d1 formed by penetrating a second connection part 21a3; and a plurality of female threaded members 51 to be inserted into the plurality of second through-holes 21d1, respectively. The first through-hole 21c1 allows a shaft part of a first corresponding screw 41 to be penetrated therethrough. The inner diameter of the first through-hole 21c1 is made larger than the shaft part of the first corresponding screw 41 and smaller than a head part of the first corresponding screw 41. The inner diameter of the second through-hole 21d1 is made larger than the head part of the first corresponding screw 41. The female threaded member 51 includes: a cylindrical part 51a on the inner peripheral surface of which a female screw is formed, that is engaged with a male screw of a second screw 42; and a locking part 51b which is formed integrally with the cylindrical part 51a and locked with the second connection part 21a3. <P>COPYRIGHT: (C)2013,JPO&INPIT |
