Claims

[Scope of Claim for Utility Model Registration] A cup frame having a cylindrical shape with a bottom, a bearing attached to the center of the bottom, and a groove for pulling out lead wires on the circumference; a base frame to which a bearing is attached and which integrally has an attachment part protruding radially outward from the circumferential surface of the cup frame, and a fixing hole is formed in the attachment part; a stator housed in the cup frame; A stepping motor comprising: a rotor disposed within a stator and rotatably supported via a motor shaft by respective bearings provided on the cup frame and the base frame; A flange portion having a step with respect to the opening portion of the cup frame and rotatable in the circumferential direction relative to the opening portion of the cup frame so that the flange portion can be inserted is integrally formed, and the flange portion is inserted into the opening portion of the cup frame. At the same time, by arranging the mounting portion to face the opening surface of the cup frame, the base frame can be rotated in the circumferential direction with respect to the cup frame, and the opening edge of the cup frame is caulked to press the flange portion. A stepping motor characterized in that the stator is sandwiched between the base frame and the cup frame, and the base frame is fixed to the cup frame by caulking.
