Patent ID: 8109487

Claim:
A linear solenoid device comprising: an energizable coil; a movable core; a first fixed core as a magnetic member having a recess capable of accommodating one end of the movable core; a second fixed core as a magnetic member having an inner peripheral surface slidably supporting the movable core; and an annular non-magnetic member coaxially connecting the first fixed core and the second fixed core to each other, wherein: the linear solenoid device is capable of being driven by an attraction force applied to the movable core towards the first fixed core upon energization of the coil, the non-magnetic member is formed so that an inner peripheral surface of the non-magnetic member functions together with the inner peripheral surface of the second fixed core as a sliding surface along which the movable core is slidable, the first fixed core has a tapered portion having an outer diameter reduced toward an opening end of the recess, and the non-magnetic member is joined to the first fixed core at an abutting portion formed on an outer periphery of the non-magnetic member configured such that the non-magnetic member does not abut on the tapered portion, and the tapered portion fits within the non-magnetic member.
