Title: Sealing garter ring
Inventor: KASHIMA MITSUHIRO
IPC: F16F9/36
Filed: 1998-09-24
Abstract: PROBLEM TO BE SOLVED: To exactly set a tightening force of a seal member and freely adjust a size of a slide friction of a slide body by forming a cross sectional shape into a U shape and positioning the curved portion on the inner periphery side and attachably/detachably disposed to/from the seal member. SOLUTION: A cross sectional shape of a garter ring 17 is formed into a U shape and the curved portion is positioned on the inner periphery side and the garter ring 17 is attachably/detachably disposed to/from a seal member S. An inner diameter dimension of the garter ring 17 is smaller than an inner diameter dimension of an outer periphery groove of a lip portion 15 at the time of a freedom. Thereby, when the garter ring 17 is engaged with the outer periphery groove of the lip portion 15, the inner diameter dimension of the lip portion 15 is reduced. Therefore, when the lip portion 15 is assembled to a piston rod 4, a tightening force is caused in the lip portion 15 to ensure a tightening margin of the piston rod 4. Thereby, the tightening force of the seal member S can be exactly set by adjusting the inner diameter of the garter ring 17.  A size of a slide friction of a sliding body can be freely adjusted by varying the inner diameter of the garter ring 17.
