<P>PROBLEM TO BE SOLVED: To provide a power transmission device of a compressor, which prevents breakage on assembling and is reduced in size. <P>SOLUTION: The power transmission device consists of: a pulley 11 rotatably attached to a casing 16 of the compressor; a hub 12 integrally rotatably connected with the pulley 11; a cylindrical member 14 provided between the hub 12 and a rotation shaft 15 of the compressor; and a spacer 21 press-fit and fixed to the rotation shaft 15. An inner circumference surface of the cylindrical member 14 and an outer circumference surface of the rotation shaft 15 are connected with screw and an inner circumference surface of the hub 12 and an outer circumference surface of the cylindrical member 14 are connected with spline. A cylindrical member contacting surface 14f as a contacting part for contacting with a shaft side seating surface 21a formed at the spacer 21 in an axial direction is provided at a collar part 14b formed at the cylindrical member 14, and the hub 12 is fixed to the cylindrical member 14 with a bolt 22. <P>COPYRIGHT: (C)2009,JPO&INPIT |
