The receiver 40 comprises a projecting cylinder part 170 inserted into an opening part 135 of a fixture 32 of the abrading unit 30, an opening and closing member 180, and a regulation member 190 regulating a movement of the opening and closing member 180 toward a closing direction. The opening and closing member 180 comprises a pair of engagement parts 182 that project from a pair of opening parts 174 of the projecting cylinder part 170 and are engageable with stopper parts 134 and an energizing member 181 energizing a pair of the engagement parts 182 to open the opening and closing member 180. When the opening and closing member 180 is in an open state, the projecting cylinder part 170 is inhibited to withdraw from the opening part 135 by engaging action of a pair of the engagement parts 182 with the stopper parts 134 and when the opening and closing part 180 is in a closed state, the projecting cylinder part 170 is allowed to withdraw from the opening part 135 of the fixture 32.SELECTED DRAWING: Figure 6
