Japanese Patent JP2023006261

A

To enhance a degree of freedom of an arrangement of parts in an internal space of a case for accommodating an output shaft support member, a motor, and a transmission mechanism.SOLUTION: A case 9 of an opening/closing member drive unit 1 is constituted by laminating a first case 21, an intermediate case 22, and a second case 23 in a first direction Z. An output shaft support member 24 arranged in the intermediate case 22 comprises a fixing part 72 extending in the first direction Z. The fixing part 72 comprises a come-off prevention part 74 locked to a protrusion 70 which is formed at an inside face 32b of the intermediate case 22, and a tip part 73a which is aligned with the protrusion 70 in a direction intersecting with the first direction Z. By attaching a reinforcing member 35 to the intermediate case 22, the tip part 73a and the protrusion 70 are fit into a notched part 75 which is formed at an edge of the reinforcing member 35. By this constitution, the movement of the fixing part 72 is regulated and coming-off of the come-off prevention part 74 from the protrusion 70 is regulated, and thereby the output shaft support member 24 is fixed to the intermediate case 22.SELECTED DRAWING: Figure 7
