PURPOSE:To improve the precision in a positioning and to improve an assemblability by bringing a housing into surface-contact with the inner wall surface of an enclosure and performing the housing positioning with projecting section of the enclosure inner wall surface. CONSTITUTION:The positioning of a housing 34, which holds a shaft 33 in a rotation free manner, in the inner wall surface direction of an enclosure 31 is performed by bringing the housing into contact a protrusion 35 of the enclosure 31. Thus, the precision in positioning is good. Moreover, the housing 34 is in contact with the inner wall surface of the enclosure 31. Therefore, no deformation is generated by tightening a first screw 37 and a second screw 38 and the generation of an off-track is prevented. |
