RUBBER BUFFER MEMBER AND BUCKET CYLINDER

PROBLEM TO BE SOLVED: To provide a rubber buffer member capable of preventing the generation of objectionable noises. SOLUTION: This rubber buffer member 10 includes: first and second annular abutting surfaces 11 and 12 with a predetermined area; a peripheral surface 13 which is positioned between the abutting surfaces 11 and 12 and elongated in a circumferential direction; an insertion hole 14 which is formed in the central portions of the abutting surfaces 11 and 12; and a cut 16 which is radially elongated toward the insertion hole 14 from the peripheral surface 13. In the rubber buffer member 10, an exposed portion, exposed on the outside from a cylinder tube, of a cylinder rod of a bucket cylinder attached to a backhoe is inserted into the insertion hole 14; the plurality of buffer members 10 are arranged in the state of overlapping one another in the axial direction of the exposed portion; and an axial thickness dimension in the overlap state of the buffer members 10 is slightly larger than an axial exposure dimension of the exposed portion of the cylinder rod in the maximum opening of the bucket.
