Abstract: An electric actuator includes: a motor unit; a speed reducer; a circuit board; a busbar; and a housing. The housing has a motor case and a circuit board case attached to one side of the motor case in an axial direction. The circuit board case has a bottom wall blocking an opening of the motor case. The bottom wall has a bottom wall through-hole that penetrates through the bottom wall in the axial direction on an outer side beyond the speed reducer in the radial direction. A busbar has a busbar main body section, a coil line connecting section to which a coil line extending on one side in the axial direction from a coil is connected, and a connection terminal section. The connection terminal section extends to one side of the bottom wall in the axial direction via the bottom wall through-hole and is connected to the circuit board.

Abstract: An electric actuator includes: a motor unit that has a motor shaft and a rotor main body; a speed reducer; a circuit board; an output section; a detection target section; a motor unit sensor; a preload member; and a support section. The motor shaft passes through a through-hole and penetrates through the circuit board in an axial direction. The detection target section is attached to a portion, which protrudes to one side in the axial direction beyond the circuit board, of the motor shaft. The detection target section faces a surface of the circuit board via a gap. The motor unit sensor is fixed to a portion, which faces the detection target section via a gap, of a surface of the circuit board. The preload member applies a preload to the motor shaft toward the other side in the axial direction and presses the motor shaft against the support section.
