Abstract
An electromagnetic actuator includes a stator, a coil for excitation, a mover, a shaft of a single outer diameter, and a buffer unit. The mover moves in a predetermined axis direction to move to an actuation position due to energization of the coil and return to a rest position due to non-energization of the coil. The shaft is fixed to the mover and exerts a driving force to outside. The buffer unit is held at the mover and positions the mover at the rest position while absorbing impact when the mover returns to the rest position. The buffer unit includes: a rod abutting against the stator at the rest position; a biasing member biasing the rod toward the stator; and a buffer member interposed between the rod and the shaft. The mover includes a fitting hole into which the shaft is fitted and a receiving part receiving the biasing member.
