Japanese Patent JP7215374
Kind Code:
B2
Abstract:
To provide a motor capable of suppressing the deterioration of durability of a driving side elastic member provided on an inner peripheral surface of a driving shaft insertion hole.SOLUTION: A coupling member 62 is equipped with a driving shaft insertion hole 72 with which a driving side inserting portion 31 of a rotary shaft 24 is engaged in a rotating direction. The driving side inserting portion 31 has a width across flat portion 32 of a width across flat shape equipped with an outer peripheral surface having a pair of plane portions 32a and a pair of curved surface portions 32b. The driving shaft insertion hole 72 has a width across flat hole portion 72a which forms a width across flat shape equipped with an inner peripheral surface having a pair of coupling plane portions 72c and a pair of coupling curved surface portions 72d, and in which the width across flat portion 32 is inserted. Between the plane portion 32a and the coupling plane portion 72c opposite to each other, and between the curved surface portion 32b and the coupling curved surface portion 72d opposite to each other, a driving side permission gap G1 is provided. The coupling curved surface portion 72d is provided with a driving side elastic member 74 having elasticity and pressing the curved surface portion 32b inward in a diametrical direction. Both end portions in a circumferential direction of the coupling plane portion 72c is exposed to the inside of the driving shaft insertion hole 72.SELECTED DRAWING: Figure 6
