Claims

[Scope of utility model registration request]

a base body, a rotary member on which the base body is rotatably supported, and a rear end joined to a distal end portion of the rotary member in a state where the base body is biased in a direction away from the rotary member along a rotation center axis. and a tightening member having an engaging portion at its tip end capable of engaging with the head of the fastening member; a guide member whose rear end is joined to the distal end of the tightening member and has a guide recess at the distal end that expands in a conical shape from the distal end of the engagement portion; each of the rotating member and the tightening member; and an elastic vibration absorbing member formed into a cylindrical shape through which the fastening member is inserted, the rear end of which is connected to the base body, and the front end of which rotatably engages with the fastening member. attached device.
