PROBLEM TO BE SOLVED: To certainly and easily perform assembling/disassembling of a seal part in a supercharger capable of only exchanging the seal part when the seal part is worn. SOLUTION: In the seal bushing assembling/disassembling device of the turbine rotor for the supercharger, a seal bushing 42 is press-fitted and removed to a neck part 32 of a turbine shaft 41. The device is constituted by a bushing pushing cylinder fitted to the turbine shaft and capable of being abutted on an end surface of the seal bushing; a holder divided to a plurality of parts, externally fitted to the bushing pushing cylinder and capable of being fitted to grooves 34, 35 formed on the seal bushing; and a bind ring externally fitted to the holders and integrating the holders. The holder for retaining the seal bushing is guided to the turbine shaft through the bushing pushing cylinder at press-fitting and removal. COPYRIGHT: (C)2008,JPO&INPIT
