PURPOSE:To easily assemble and disassemble a gear, a pulley and the like adapted to attached to a motor so as to facilitate the sorting and collection of plastic materials used therefor. CONSTITUTION:A spur gear 101, formed therein a shaft hole 10 having the same sectional shape as that of a rotation checking part provided thereon with face cut parts 22a, 22b of the output shaft 21 of a motor 2, is limited in axial movement by a shoulder part 22c at the terminal ends of the face cut parts 22a, 22b, and a locking member 5. Accordingly, the gear 101 may be fitted on the output shaft 21 of the motor 2 without using a fastening member such as a screw or the like. With this arrangement, plastic materials used in the attachment and removable of the spur gear 10a and the output shaft 21 of the motor 2 and for the spur gear itself may be sorted and collected so as to be easily reused. |
