Abstract
Cutouts are formed in a front end plate disposed of a motor body. A thrust member, which has a hump segment to touch and press against a rear end surface of a rotary shaft frontward, is detachably attached to the motor body such that distal ends of arm segments of the thrust member are fitted into respective cutouts of the front end plate.
Claims15
A thrust member of a motor including a motor body which is shaped substantially cylindrical, and a rotary shaft which has a front end portion thereof sticking out from a front end face of the motor body, has a rear end face thereof exposed at a rear end face of the motor body, and which rotates with respect to the motor body, the thrust member comprising:
- a plurality of arm segments attached to predetermined areas on an outer surface of the motor body;
- a hump segment to touch the rear end face of the rotary shaft when the thrust member is mounted on the motor with the arm segments being attached to the predetermined areas on the outer surface of the motor body;
- and
- a plurality of shoulder segments to bridge the arm segments and the hump segment and to urge the hump segment toward the rotary shaft.
A motor, comprising:
- a rotary shaft;
- and
- a motor body which is shaped substantially cylindrical, includes a rotor that is fixedly attached to a predetermined area of the rotary shaft, and a stator that is shaped hollow-cylindrical, and that houses the rotor and acts on the rotor in a non-contact manner so as to cause the rotor to rotate around the rotary shaft as an axis, wherein the rotary shaft has a front end portion thereof sticking out from a front end face of the motor body, and has a rear end face thereof exposed at a rear end face of the motor body, the motor body having, at an outer surface thereof, a thrust member receiving mechanism, to which a thrust member is attached that includes a hump segment to touch the rear end face of the rotary shaft, and that urges the hump segment toward the rotary shaft.
