| 发明名称 | Rotary actuator | ||
| 摘要 | A rotary actuator includes a rotation shaft rotatably driven by a motor, an internal gear provided on an outer side of the rotation shaft in a radial direction of the rotation shaft, a rotation output section provided between the rotation shaft and the internal gear in the radial direction to reduce a rotation speed outputted from the rotation shaft and to output a power in conjunction with the internal gear, a cylindrical housing portion fixed to the internal gear, and an attachment member integrated with an outer wall of the housing portion. The internal gear has a protrusion protruding from an outer wall of the internal gear, and the housing portion has a recess into which the protrusion is inserted. The attachment member has an attachment hole that is different from the recess in position in a circumferential direction of the housing portion. | ||

| 主权项 | 1. A rotary actuator comprising: a motor; a rotation shaft rotatably driven by the motor; an internal gear incapable of rotating, provided on an outer side of the rotation shaft in a radial direction of the rotation shaft; a rotation output section provided between the rotation shaft and the internal gear in the radial direction to reduce a rotation speed outputted from the rotation shaft and to output a power in conjunction with the internal gear; a housing portion having a cylindrical shape, and fixed to the internal gear located on an inner side of the housing portion in the radial direction; and an attachment member integrated with an outer wall of the housing portion, wherein the internal gear has a protrusion protruding from an outer wall of the internal gear, the housing portion has a recess into which the protrusion is inserted, the attachment member has an attachment hole that is different from the recess in position in a circumferential direction of the housing portion, the attachment hole is separated from the recess in the circumferential direction, and the housing portion does not have a recess that overlaps the attachment hole in the radial direction and into which the protrusion is inserted. | ||
