Claims

[Claims for Utility Model Registration] (1) A stepping motor comprising a stator including a coil and a stator yoke for housing the coil, and a rotor rotatably held within the stator, A stepping motor characterized in that a member constituting a stator yoke and another member adjacent to one component of the stator yoke are joined by caulking. (2) In the statement of claim (1) of the utility model registration, the caulking includes a through hole formed in one member and a protrusion that can be inserted into the through hole formed in the other member. A stepping motor is characterized by the fact that it operates between (3) A stepping motor as set forth in claim (1) of the utility model registration, characterized in that the adjacent member is a member constituting another stator yoke. (4) The stepping motor as set forth in claim (1) of the utility model registration, characterized in that the adjacent member is a mounting plate for attaching the stepping motor main body to the apparatus side.
