The solenoid actuator for operating a clutch in a rotating device is equipped with: a solenoid that is symmetrical with respect to the axis; a plunger, which is a plunger that fits together slidably with the solenoid and is able to move in the axial direction from a first position that allows the clutch to be disengaged to a second position in which the clutch is engaged, the plunger being provided with a first portion that is obtained from a magnetic material and fits together with the solenoid slidably facing same, wherein the first portion forms a circle around the axis and has a first end facing the clutch, and with a second portion that is obtained from a non-magnetic material, is fixedly fitted together with the first portion and has a first end section that is parallel to the first end; and a wall surface, which is a wall surface against which the plunger abuts when the plunger is in the second position, the wall surface being provided with a first surface against which the first end section of the second portion abuts and a first surface that is set back in the axial direction from the first surface and for which contact with the first end of the first portion is prevented. |
