PROBLEM TO BE SOLVED: To attain weight reduction in a coreless motor by reducing metal parts, size reduction by using low parts, cost reduction by saving man-hours and the time necessary for assemblying, and attain high accuracy by improving assembly accuracy. SOLUTION: A cylindrical motor housing 1 is formed, which has a through- hole 1b in the center of a closed surface 1a, and a resin mold body 3 consisting of a retaining part 31 clamping the closed surface 1a from both of the inside and the outside via the through-hole 1 in the motor housing 1 and having a bearing hole 30 for permitting the rotating shaft 2 to be inserted, and a sleeve 32, extending from the retaining part 31 to the inside of the motor housing 1, is assembled as a bearing and a bearing house of a rotatary shaft 2.
