Clearance adjusting member

Abstract

To provide a clearance adjusting member that allows for easy attaching and detaching works and has no risk of falling off from a pin. A clearance adjusting member, in a pin coupling structure in which a first member and a second member are coupled freely to be rotated in relation to each other by a cylindrical pin, for adjusting an axial clearance between the first member and the second member, the clearance adjusting member comprises a shim in a U-shape or C-shape attached to the pin in the axial clearance, and a restricting means for restricting the shim so as to be freely releasable. A restricted piece protruding radially outward is formed on an outer circumferential edge of the shim. The restricting means includes a pair of restricting pieces spacedly arranged circumferentially on the radially outer side of the pin. One-side slanting piece extending by slanting to the direction of axial one-side towards a circumferential one-side is provided at a circumferential one-side end portion of one restricting piece. Another-side slanting piece extending by slanting to the direction of an axial one-side towards a circumferential another-side is provided at the circumferential another-side end portion of the restricting piece of another side. When the shim is inserted towards the axial clearance, the restricted piece pushes and rides over while elastically deforming the one-side slanting piece towards the circumferential one-side, or the restricted piece pushes and rides over while elastically deforming the another-side slanting piece towards the circumferential another-side, and thereby the restricted piece is positioned between the pair of restricting pieces and the shim is attached to the pin.
