The holding member 1 has a contact side 2 formed by bending one end of a metal plate into a substantially U-shaped or V-shaped cross section. First clamping member 1
A cantilevered support shaft 3 extending in a direction parallel to the abutting side 2 is planted at a position separated from the abutting side 2 by a width equal to or larger than the width of the pipe strut a which is an object to be clamped.

The second sandwiching member 4 is formed by bending both sides of the metal plate to form both sleeve edges 5.
It has a U-shaped cross section. One end in the lengthwise direction is formed in a receiving recess 6 having a shape matching the peripheral wall of the column a, and the other end in the lengthwise direction is formed in an open leg shape with both sleeve edges 5 left. The second holding member 4 is rotatably supported on the cantilever support shaft 3 at a position near the receiving recess 6.

A mounting member 8 for a lighting fixture or the like is formed in a hollow shape, and a fixed leg 7 is passed between both sleeve edges 5 of the second holding member 4 formed in the open leg shape, and is rotatably connected thereto. .

As shown in FIG. 4, the mounting member 8 has a suspension screw 12 which is fitted into the circumferential groove 11 of the instrument shaft foot 10 which is inserted into the hollow portion 9.
And a rotation stop screw 13 which is pressed against the outer peripheral wall of the shaft foot 10.

As shown in FIG. 3, an example of the instrument shaft foot 10 is provided with a lamp socket 15 at a tip end thereof via a free metal fitting 14 made of a saddle type metal fitting so as to be swingable by a support shaft 16.

According to the embodiment having such a configuration, the instrument shaft foot 10 is inserted into the hollow cylindrical portion of the mounting member 8, and the shaft 12 is screwed under the alignment of the suspension screw 12 and the circumferential groove 11. The foot 10, that is, the lamp socket 15 is rotatably mounted around the axis, and the rotation stop screw 13 is lightly tightened to temporarily fix it.

The first pinching member 1 in such a state is laterally applied to the column a with a gap between the contact side 2 and the second pinching member 4 in a parallel posture, and the column a is connected to the contact side 2 and the second side. It is inserted between the holding member 4.

A turning action force is generated in the second holding member 4 in which the pillar a is inserted so that the tip end (on the side of the mounting member 8) on which the load is applied descends, whereby the receiving recess 6 at the other end contacts the pillar a. And the peripheral wall of the pillar a is surrounded and sandwiched between the abutting side 2 and the receiving concave portion 6 (second shown state).
