Abstract
An electromagnetic actuator including: an outer tubular member and an inner axial member connected by an elastic member; a coil member attached to the outer tubular member generating electromagnetic force through energization thereto; a magnet member attached to the inner axial member and subjected to the electromagnetic force to exert axial driving force between the inner axial member and the outer tubular member; a first support section provided at the outer tubular member to axially clamp and securely support the coil member; a synthetic resin annular member housed within the outer tubular member including a power feed terminal to the coil member; and a second support section provided at the outer tubular member to axially clamp and securely support the annular member in such a parallel structure that clamping force by the first support section is not exerted on the second support section.
