Title:
PISTON FOR SHOCK ABSORBER
Document Type and Number:
WIPO Patent Application WO/2004/079221
Kind Code:
A1
Abstract:
This invention relates to a piston for, for example, a vehicular shock absorber. The piston for a shock absorber according to the present invention consists of a piston body and a piston ring fitted around an outer circumferential surface of the piston body, and a bent portion constituting one end portion of the piston is fitted in a first groove in the piston body. This first groove is defined by both end surfaces extending at right angles to the axis of the piston body, and a bottom surface connecting these end surfaces together, and a free end part of the bent portion is engaged with a corner portion defined by the left end surface and the bottom surface thereof. According to the present invention described above, the free end part of the bent portion is not likely to move in the radially outward direction as compared with a corresponding part of a conventional piston of this kind in which a left end surface of a similar groove consists of a tapering surface. Therefore, the bent portion will not come off from the first groove.
