Abstract

A solenoid device includes a yoke, a core, a shaft, a bobbin, a coil, a plunger, a lid, and a housing. A housing body part of the housing has a first opening; a cylindrical first inner wall part having a first step part extending toward the outer side in the radial direction; and a cylindrical second inner wall part having a second step part extending toward the outer side in the radial direction. A first cylindrical part has a first flange part. The outer diameter of the first flange part is larger than the inner diameter of the first inner wall part and smaller than the inner diameter of the second inner wall part. A circumferential end part of the first flange part contacts the second step part. The lid is non-magnetic, and a circumferential edge part is held between the first step part and the first flange part.
