Document Type and Number:
Japanese Patent JP2022113319
Kind Code:
A
Abstract:
To provide an electric actuator that can built a magnetic sensor to a stator with a high positional accuracy.SOLUTION: The electric actuator includes a motor unit, a bus bar, a bus bar holder, a magnetic sensor, and a circuit board. The bus holder has a cylindrical part surrounding an outer peripheral surface of the stator. In the outer peripheral surface of the stator, there are formed a first regulation wall surface facing one side in a peripheral direction and a second regulation wall surface facing the other side in the peripheral direction. In an inner peripheral surface of the cylindrical part, there are a first contact surface in contact with the first regulation wall surface and a second contact surface in contact with the second regulation wall surface.SELECTED DRAWING: Figure 2
