<P>PROBLEM TO BE SOLVED: To provide a positioning structure that allows a difference in radial thermal strain generated between a scroll housing and a bearing housing with a simple configuration, and can fix movement in a rotation direction while preventing excessive shear force from acting on a positioning pin. <P>SOLUTION: Radially facing surfaces 16a, 16b facing each other on the faces parallel to the axial line of a supercharger are formed between a turbine housing 7 and a bearing housing 2 constituting a supercharger. A pin hole 18 radially extending is formed on one radially facing surface 16b. A positioning groove 19 is formed on the other radially facing surface 16a, the groove including an opening 19' conforming to the pin hole 18, extending in the axial direction of the supercharger and having an open end. The turbine housing 7 and the bearing housing 2 are fastened by fitting the positioning groove 19 to a protruding portion 20' of a positioning pin 20 partially inserted into the pin hole 18. <P>COPYRIGHT: (C)2013,JPO&INPIT |
