Abstract
An actuator device includes a drive motor, gears and pairs of rotary shafts. The gears are rotated by torque outputted from the drive motor. Each pair of rotary shafts corresponds to one of the gears. The rotary shafts in each pair extend from both axial sides of the corresponding gear, respectively. At least two of the rotary shafts function as output shafts that are capable of outputting the torque of the corresponding gear or gears to the outside. This is capable of dealing with various requirements.
Claims17
An actuator device, comprising:
- a drive motor;
- a plurality of gears that are rotated by torque outputted from the drive motor;
- pairs of rotary shafts, each pair corresponding to one of the gears, wherein the rotary shafts in each pair extend from both axial sides of the corresponding gear, respectively, and wherein at least two of the rotary shafts function as output shafts that are capable of outputting the torque of the corresponding gear or gears to the outside;
- and
- a housing for accommodating the gears, wherein the rotary shafts functioning as the output shafts extend in different directions from the corresponding gear or gears, wherein the housing includes opposing walls, wherein one of the rotary shafts functioning as the output shafts projects from one of the opposing walls, and the other rotary shaft functioning as the output shaft does not project from either of the opposing walls.
