Abstract:
A step motor (6) comprising a motor main body (63) that applies rotational drive force to a rotating body (4); a motor casing (60) housing the motor main body; and a motor base plate (64) holding the motor casing. The motor base plate has: a mounting surface (640) having the motor main body mounted thereto via the motor casing; a locking surface (641) on the opposite side to the mounting surface; and locking holes (642) penetrating between the mounting surface and the locking surface. The motor casing has locking arms (615) and locking hooks (616, 2616). The locking arms are inserted into the locking holes in an elastically deformed state in which the locking arms are extended diagonally relative to the mounting surface and the locking surface. The locking hooks: form contact surfaces (616a, 2616a) that extend diagonally relative to the mounting surface and the locking surface; and are locked to the motor base plate in a state in which the contact surfaces are caused to come in contact with locking corner sections (644) formed by the locking surface and the locking holes in the motor base plate.
