Abstract

A sliding hole is formed so that a screw portion can pass therethrough. Also, a seal member is provided at a portion, through which the screw portion placed in the sliding hole can pass and in which a sliding portion does not slide.

Claims

1. A motor comprising:

a stator provided with a coil to be supplied with electric current;

a resin rotor adapted to rotate in said stator and provided with a magnet;

an output shaft having a screw portion to be screwed into a threaded hole provided in said rotor;

a regulating portion for axially moving said output shaft by regulating rotation of said output shaft and for sliding and holding said output shaft;

a sliding portion, provided in said output shaft and adapted to slide in a sliding hole provided in said regulating portion; and

a metallic stopper, provided in said rotor and adapted to abut against said output shaft, for axially regulating said output shaft.

2. The motor according to claim 1, wherein said stopper axially abuts against said output shaft.

3. The motor according to claim 1, wherein said stopper is insert-molded into and fixed to said rotor.
