Title:
LINEAR MOTION ROD, LINKING MEMBER, PISTON, AND PISTON-FASTENING STRUCTURE
Document Type and Number:
WIPO Patent Application WO/2016/039307
Kind Code:
A1
Abstract:
On a piston rod, a rod-side linking region, the cross-section of which is a non-circular shape when viewed from the axial direction, is formed on the shaft. A washer (linking member) has an insertion hole with a non-circular shape to allow the insertion hole to be engaged with the rod-side linking region in the circumferential direction. The washer is also configured to have an engaging structure for engaging with a piston in the circumferential direction. As a result, displacement or separation of the piston from the piston rod is reliably prevented with a simple structure.
