  Reference numeral c denotes a socket driver c that penetrates the large-diameter through hole 18 and the small-diameter through hole 19 of the inner collar b, and has the following configuration.

  That is, the nut-inserted portion 5 is fitted to the drive portion 20 with the shank 21 that passes through the large-diameter through hole 18 and the small-diameter through hole 19 of the inner collar b, and the end portion opposite to the shank 21 of the drive portion 20. The head 22 having a shape that can be inserted is integrally formed.

  Further, in the present invention, a spring 23 is inserted into the storage portion 12 of the outer collar a. A pin 24 with a head 25 is inserted into the spring 23.

  It is a condition that the tip of the pin 24 inserted as described above is inserted into the recess 17 of the inner collar b.

  d is a hollow outer ring body into which the outer collar a is inserted, and has the following configuration.

  That is, the hollow outer ring body d is provided with a locking portion 26 that is locked by the stopper ring 11 at one end 1c.

  And the said ring body d protrudes in the inner side part by the press part 27 which presses the said pin 24 with the head 25, when the said latching | locking part 26 is latched by the said ring 11 for stoppers.

  The above configuration is the configuration of the hollow outer ring body d.
