PROBLEM TO BE SOLVED: To absorb a dimension error at the time of working a pivot or a pivot hole by cutting-off corners on the outer peripheral wall at the side of a nearly box- shaped bottom wall as a whole, swelling the outer end edges of an opening part in an almost circular arc shape and projectingly providing vertical projecting lines on an inner peripheral surface. SOLUTION: The corners of the outer peripheral wall 11 at the side of the bottom wall of a funeral tool spacer 1 are cut-off to be the recessed one with circular arc shape, corner cut-off parts 12 are swelled outward in the shape of the inscribed circle of the outer peripheral wall, and the projecting lines 13 with a triangular cross section are vertically and projectingly arranged in each center part. Then, the outer end edges 15 of the opening part 14 in the funeral tool spacer 1 is swelled in the nearly circular arc shape, oblique chamfering is executed in the whole periphery in the inner peripheral edge of the opening edge 14 and the nearly trapezoid-shaped projecting lines 17 are arranged in a vertical direction on the inner peripheral wall 16. Thus, the dimension error at the time of working the pivot or the pivot hole is absorbed, attachment/detachment is easily executed, and the play and coming-off of a carrying handle or a support leg are prevented.
