<p>PURPOSE:To make the area necessary for fitting small and miniaturize the device by surrounding a fixed drum with the annular part of a fitting member, and supporting the fixed drum by plural fitting parts extending inward provided in the annular part. CONSTITUTION:A fitting member 27 that fixes a fixed drum 4 consists of an annular part 28 that surrounds the drum 4 in radial direction, plural fitting parts 29 extending in radial direction and a bracket 3 extending outward. When a positioning pin 32 is fitted to a positioning hole provided in the stepped part of th fixed drum 4 and a screw 36 is tightened in fitting, mutual relation of the fitting member and drum 4 is maintained exactly and fixed. Then, a pin 39 is fitted to the positioning hole of a chassis, and the bracket 3 is fixed to the chassis with a screw 38. Thus, the space required for fitting becomes small, and the device can be miniaturized.</p> |
