SLIDINGLY MOVABLE MOUNT ASSEMBLY OF EXTENSIBLE/ CONTRACTIBLE PART

摘要

PROBLEM TO BE SOLVED: To reliably fix a sliding shoe by forming a lengthwise groove to house a spacer in one of an outside surface among the sliding shoe opposed to one of mutually opposing slidingly movable surface parts while being constituted in a shape of being fixed in the circumferential direction by the sandwiching action between extensible/contractible parts. SOLUTION: For example, a sliding shoe 13 does not slip in the circumferential direction when being fixed by the sandwiching action between an inside extensible/ contractible part 11 and a collar 12 by being adjusted to an opposed surface of the collar 12 and the inside extensible/contractible part 11 to slidingly move the collar 12 by inserting a contour part shape into an outside extensible/contractible part. A rectangular strip-shaped spacer 14 is inserted into a lengthwise groove 16 formed on an outside surface of the sliding shoe 13 opposed to the collar 12. By this constitution, the load distribution is uniformized in the circumferential direction by the cantilever length of the sliding shoe 13 and air gaps 15 and 15a still remaining between an inner wall of the collar 12 and an outside surface area of the sliding shoe 13 in a lengthwise groove 16-nonexistent part of the sliding shoe 13 influencing the load distribution by a configurational change in the inside extensible/contractible part 11.
