Title:
SOLENOID, DAMPING FORCE ADJUSTMENT MECHANISM, AND DAMPING FORCE ADJUSTABLE DAMPER
Document Type and Number:
WIPO Patent Application WO/2022/181319
Kind Code:
A1
Abstract:
Provided is a solenoid comprising a molded coil, an anchor, and an armature. An outer circumferential projection and an inner circumferential projection are formed on the anchor. In the non-current supply state, an axial distance from the anchor to the outer circumferential part of the armature closest to the outer circumferential projection in the radial direction is shorter than an axial distance from the anchor to the inner circumferential part of the armature closest to the inner circumferential projection in the radial direction. In other words, a timing at which the outer circumferential part of the armature faces the outer circumferential projection of the anchor in the radial direction is different from a timing at which the inner circumferential part of the armature faces the inner circumferential projection of the anchor in the radial direction.
