Abstract

The invention provides a screw retaining ring. Via use of a metal plate, axial force can be set to a higher value, and reduction of the axial force caused by creep deformation and change of the axial force caused by plate thickness non-uniformity of a to-be-installed part such as a panel, etc. The screw retaining ring (10) comprises: a gasket (30) provided with a flange part (60) and a shaft part (70); and a metal plate (40) freely rotatably installed on the gasket (30), and provided with a base part with a screw thread hole (43) formed coaxial with an insertion hole (80) and a supporting foot (42) extending toward the flange part (60) and opposite to the back surface of the flange part (60). Via the shaft part (70) being inserted into an installing hole (21) of the to-be-installed part (20) such as the panel, a self-tapping screw (50) is screwed into the screw thread hole (43), the metal plate (40) is made to rotate and move axially, and therefore, the to-be-installed part (20) is clamped by the back surface of the flange part (60) and the supporting foot (42).

Description

technical field

[0001] The present invention relates to a screw retainer. By using a metal plate, not only can the axial force be set high, but also the decrease of the axial force due to creep and the unevenness of the plate thickness of the mounted parts such as panels can be suppressed. The resulting change in axial force. Background technique

[0002] In the past, there is known a first screw buckle in which the front end portion enters the inner side of the leg portion by fastening the screw so as to expand the leg portion (for example, refer to paragraph 0018 of Patent Document 1, Figure 4 and Figure 5 ).

[0003] Conventionally, there is known a second screw buckle deformed so that the pillar protrudes by screwing (for example, refer to paragraph 0010 of Patent Document 2, Figure 10 and Figure 11 ).

[0004] In the past, when a bolt is inserted, the rotating nut is rotated so that the rotating nut is raised by bolt tightening (for example, refer to paragraph 0...
