Title:
DAMPER AND METHOD FOR ASSEMBLING DAMPER
Document Type and Number:
WIPO Patent Application WO/2017/073218
Kind Code:
A1
Abstract:
Provided are: a damper configured so that the axial play between a coil case and a case member can be eliminated without increasing the size of a solenoid; and a method for assembling the damper.
A damper is configured so that: an O-ring 85 (seal member) will be elastically supported by a tapered hole 84 which is formed in the inner peripheral surface 94 of a case member 71, and also by a tapered shaft 89 which is formed on the outer peripheral surface 92 of a coil case 61; and an axial force generated by the O-ring 85 will be received by a retaining ring 91. The configuration can eliminate the play between the coil case 61 and the case member 71, which constitute a solenoid 33. As a result, a damping force regulation mechanism 31, and in turn the damper 1, can be made more compact than when the O-ring 85 is received by the opening 83-side end surface of the case member 71.
