A first member is disposed between and pivotally connected to a pair of spaced apart parallel portions of a second member through means of a pivot pin extending through axially aligned holes respectively located in the first member and in the parallel portions of the second member. The hole in the first member has a bushing located therein which is shorter than the hole, and first and second pairs of opposed Belleville springs are received on the pin and are respectively compressed into the hole at the opposite ends of and into sealing engagement with the opposite ends of the bushing through means of first and second pairs of wedge pieces respectively interposed between opposite sides of the first member and the parallel portions of the second member.
