Abstract
In a motor device, a ground terminal is provided to be clamped between a motor case and a gear case, and electrical noise generated due to rotation of a rotating shaft flows through the ground terminal. First to third fixing parts disposed around the rotating shaft and composed of first to third motor case-side abutting surfaces and first to third gear case-side abutting surfaces abutted against each other are provided between the motor case and the gear case. The ground terminal is disposed only between the second fixing part and the third fixing part which form a shortest line segment among line segments connecting the first to third fixing parts adjacent to each other in a circumferential direction of the rotating shaft.
Claims6
A motor device comprising:
- a rotating shaft;
- and
- a gear rotated by the rotating shaft,
- the motor device comprising:
- a motor case accommodating the rotating shaft;
- a gear case accommodating the gear;
- and
- a conductive member that is clamped between the motor case and the gear case and through which electrical noise generated due to rotation of the rotating shaft flows, wherein
- at least three fixing parts disposed around the rotating shaft and each composed of a pair of abutting surfaces abutted against each other are provided between the motor case and the gear case, and
- the conductive member is disposed only between the fixing parts that form a shortest line segment among line segments connecting the fixing parts adjacent to each other in a circumferential direction of the rotating shaft.
