A movable iron core, which confronts the first and second attraction portions, is disposed displaceably in the housing. Further, in the interior of the first attraction portion, which is recessed in a concave shape, a first guide body is installed, the first guide body being formed in a cylindrical shape from a non-magnetic material, and a first rod member of the movable iron core is supported displaceably in axial directions by the first guide body. On the other hand, a cylindrically shaped second guide body is disposed on a lower end of the housing, and a second rod member of the movable iron core is supported displaceably in the axial directions by the second guide body.
