PROBLEM TO BE SOLVED: To provide a motor which assures easier fixing of an end plate to a yoke and disassembly of these elements and enables re-use of at least the expensive yoke. SOLUTION: An engaging groove 2 is formed to an end portion of the aperture side of the yoke 1 formed in the bottomed cylindrical shape, and a projection 8 formed on the end plate 7 is engaged to the groove 2. The first circumferential in-low portions 2a formed in both sides of the engaging groove 2, and the second circumferential in-low potions 8a formed in both sides of the projection 8, are placed in contact with each other for restricting movement in the circumferential direction. The first radial direction in-low portion 3 formed at the internal circumferential surface of an aperture 1a, and the second radial direction in-low portion 7a formed at the external circumferential surface of an end plate 7, are placed in contact with each other for restricting movement in the radial direction. A pawl portion 9 formed on the projection 8 is bent and is placed in contact with an engaging portion 6 at the area near the engaging groove 2, and an end of the pawl portion 9 is engaged with a groove portion 5 formed in through-hole 4. Width of the pawl portion 9 is identical to the width of the groove 5 and therefore the pawl portion 9 is restricted in the movement in the circumferential direction.
