Electric actuator

An electric actuator comprising:

• a motor that has a motor shaft extending in an axial direction;
• a speed reduction mechanism disposed on an outer side in a radial direction of a portion on one side of the motor shaft in the axial direction and connected to the motor shaft;
• a case that accommodates the motor and the speed reduction mechanism;
• an output portion to which rotation of the motor shaft is transmitted via the speed reduction mechanism;
• a first board electrically connected to the motor;
• a rotation detection device that detects rotation of the output portion;
• a connector portion provided in the case and connected to electrical wiring outside the case;
• a first wiring member electrically connected at least indirectly to the electrical wiring via the connector portion;
• and
• a second wiring member electrically connected to the rotation detection device,
• wherein the case includes
• a first case provided with the connector portion and including a first opening portion which opens on the one side in the axial direction, and
• a second case including a second opening portion which opens on the other side in the axial direction,
• the first board is accommodated in the first case,
• the rotation detection device is accommodated in the second case,
• an end portion on the one side in the axial direction of the first case and an end portion on the other side in the axial direction of the second case are fixed to each other in a state where the first opening portion and the second opening portion are opposed to each other in the axial direction,
• the first wiring member includes a first connecting portion held in the first case,
• the second wiring member includes a second connecting portion held in the second case,
• the first connecting portion is exposed on the one side of the first case in the axial direction,
• the second connecting portion is exposed on the other side of the second case in the axial direction, and
• the first connecting portion and the second connecting portion are disposed at positions overlapping in the axial direction in a state where the first case and the second case are fixed to each other, and are electrically connected to each other.
