PROBLEM TO BE SOLVED: To provide a bearing arrangement of a simple configuration in which a sliding load between a bearing and a shaft is not increased even if the fitting surface of a holding member to which the bearing is fitted is not vertical to the axial line nor the bearing is coaxial with the axis. SOLUTION: The bearing arrangement comprises a staple unit 312 that moves along a guide shaft 306 supported by a frame (holding member) 301 in which the guide shaft 306 is inserted, and a bearing 304 provided to the frame 301. The bearing 304 is swingably fitted to the frame 301 so that the bearing 304 and the guide shaft 306 faces at almost coaxial when the staple unit 312 moves. COPYRIGHT: (C)2007,JPO&INPIT
