摘要： PROBLEM TO BE SOLVED: To provide a stepping motor rotor in which another member does not exist on the outer circumferences of a rotor shaft having reduced bearing friction with a tenon having a diameter smaller than a commonly used value and a rotor magnet.
SOLUTION: This rotor is structure so that a rotor shaft made of a metal member is almost machined to have a shaft diameter equal to that of a tenon as both end portions by, for example, cernterless machining, and a resin-made rotor pinion is formed around the rotor shaft member on the one surface of a rotor magnet. Further, the rotor includes a rotation stop means for the rotor shaft of the rotor pinion and a movement preventing means in the shaft direction which are formed by crushing part of the rotor shaft or press-fitting another material into the rotor shaft at a portion contacting the rotor shaft contacts a resin material forming the rotor pinion. Still further, part of the resin material forming the rotor pinion may communicate the other surface of the rotor magnet through the hole of the magnet so as to be a rotor seat equivalent member after being cured.
