PROBLEM TO BE SOLVED: To strengthen the coupling of a cylinder case and a stator by forming a spiral groove on the cylinder case. SOLUTION: A motor case and the structure of a motor stator are configured such that the stator (4) is inserted in the spiral groove (20) formed on the internal periphery (1a) of the cylinder case (1), and resin (4A) is injected into the spiral groove (20), thus ensuring the rotation of the stator (4) relative to the cylinder case (1) and achieving the coming-off prevention of the stator.
