PROBLEM TO BE SOLVED: To obtain a motor device, which has a gear housing with which attachment legs having insertion holes whose directions are approximately perpendicular to the direction of the output shaft of a deceleration mechanism are integrally molded, without undercuts of the attachment leg parts and is easily attached to a driving object. SOLUTION: Attachment legs 40 are integrally molded with a gear housing, of which a motor device is composed. Nut-holding parts 56, which are fully opened in one of mold separation directions and bolt insertion parts 64 which are fully opened in the other mold separation direction, are formed in the attachment legs 40. Both the nut-holding parts 56 and bolt insertion parts 64 comprise insertion holes linked with each other, in directions perpendicular to an output shaft direction D of a deceleration mechanism (same direction as the mold separation direction). With this constitution, even if insertion holes are formed in directions approximately perpendicular to the output shaft direction D, undercuts of the attachment leg parts 40 will not be produced, and further, since nuts 54 are held by the nut holding parts 56, so that the motor device can be attached easily to a pipe frame. |
