The leaf spring 30 bends and deforms between both end portions due to the rotation of the jaw member 5 and swings and deforms around the proximal end portion to thereby urge the jaw member 5 to rotate in the releasing direction. Then, the jaw member 5 is urged to rotate in the direction opposite to that past the dead point.

  In addition, the bolt 31 for fixing both to the holding | maintenance position can be penetrated in the position corresponding to the lower part of the bracket 4 and the jaw member 5. FIG.

  When the supporting object M is supported on the tube P, the jaws support the supporting object M in the open state shown in FIG. 7 (the stopper 6 is in the lock position and the jaw member 5 is in the release position). The holding metal fitting 2 is applied to the tubular body P so as to receive the tubular body P in the opening 19 of the member 5, and the object to be supported M is placed in the direction in which the concave holding portion 18 of the jaw member 5 is fitted to the tubular body P. Press against P. The jaw member 5 initially rotates the stopper 6 against the spring force so that the engaging portion 20 pushes up the lock portion 25 of the stopper 6 while the plate spring 30 is bent and compressed and deformed (clockwise in the figure). Direction), the tube P is rotated to the holding position (counterclockwise in FIG. 7), and is energized by restoring and extending the leaf spring 30 beyond the dead point (FIG. 8). (Fig. 6). The stopper 6 rotates counterclockwise after the engaging portion 20 has passed, returns to the locked position, and reaches the locked state.

  In the state of FIG. 6, the gripping member 2 is biased to the holding position by the leaf spring 30, but even when a strong external force that rotates in the release direction (clockwise) is applied, the engaging portion 20 Since the jaw member 5 is prevented from rotating and restrained to the holding position by abutting against the lock portion 25 of the stopper 6, the support object M can be reliably supported on the tubular body P.
