Abstract:
An annular recess is formed in an inner periphery defining a bolt shank bore (114) and has fitted therein an annular elastic member (115) having elasticity radially thereof and having an inside diameter smaller than the outside diameter of the shank of a bolt (113). The shank bore (114) has at an intermediate part thereof a stepped portion so as to give an increased diameter to a bore portion from the intermediate part to one end of the bore, and a hollow cylindrical member for preventing the elastic member from slipping out is inserted in the shank bore (114) from the bore end so as to form a clearance between the stepped portion and the preventing member, whereby the annular recess is formed.
