DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail with reference to the illustrated embodiments. As shown in FIG. 1, the currant 1 is formed to have an insertion portion 6 at its lower end. The insertion portion 6 here is formed so as to be thinner than the outer diameter of the callan 1, and a serration 9 is provided in the upper part along the circumferential direction, and the engaging portion 2 is formed by the serration 9. As shown in FIG. 2, the engaging portion 2 is provided with a positioning projection 20 projecting outward from the serration 9, and the lower end of the positioning projection 20 is located below the lower edge of the serration 9. It protrudes. Here, the positioning projection 20 may be formed by projecting a protruding piece 20a from the outer surface of the insertion portion 6 so as to be located below the serration 9 as shown in FIG. A groove 7 is formed in the lower part of the insertion part 6 along the circumferential direction.

The mounting member 5 into which the insertion portion 6 of the callan 1 is inserted and connected is a cylindrical member having a flange 5a at the upper end of a cylindrical portion 5c, and a screw portion 5b is formed on the outer peripheral surface of the cylindrical portion 5c. A detent engaging portion 3 is formed on the inner peripheral surface, and a mounting groove 11 is formed on a lower portion of the outer peripheral surface. The mounting groove 11 extends to the inner peripheral surface of the mounting member 5 so that the elastic engaging member 8 formed by bending a metal bar into a U-shape can be fitted. The detent engaging portion 3 is formed of a serration 10 that can engage with the serration 9 that constitutes the engaging portion 2 provided on the callan 1.
By engaging the serrations 9 and the serrations 10 with each other, the callan 1 can be connected in a state in which the serrations 9 are prevented from rotating with respect to the mounting member 5. The detent groove 21 is provided with a concave groove 21 in which the positioning projection 20 is engaged so as to cut out a part of the flange 5a.

A mounting hole 12 corresponding to the outer diameter of the cylindrical portion 5c of the mounting member 5 is formed in a top plate portion 4a such as a counter as the surface 4 to be mounted. Of the mounting member 5 by inserting the seat plate 14 into the cylindrical portion 5c on the lower surface side of the counter and screwing the nut 13 into the screw portion 5b provided on the outer peripheral surface of the cylindrical portion 5c. Are attached to the attachment holes 12.

In mounting the callan 1, first, the mounting member 5 is fixed to the top plate 4a. This means that the mounting member 5 is fitted into the mounting hole 12 provided in the top plate portion 4a from above, and the seat plate 14 is attached to the cylindrical portion 5 below the top plate portion 4a.
c and the nut 13 is screwed into the threaded portion 5b of the cylindrical portion 5c.
It is performed by screwing into. Here, the engaging member 8 is fitted into the mounting groove 11 of the mounting member 5. After this, Karan 1
May be inserted into the mounting member 5. At the time of insertion, the serrations 9 as the engaging portions 2 provided on the insertion portion 6 are engaged with the serrations 10 as the detent engaging portions 3 provided on the mounting member 5, so that the rotation is stopped and the curl 1 Is attached to the mounting member 5. When the engaging portion 2 and the detent engaging portion 3 are engaged with each other, the positioning protrusion 20 is engaged with the concave groove 21. The callan 1 is attached to the mounting member 5 with the mounting direction regulated by engaging the detent engaging portion 3 with the detent engaging portion 3. The concave groove 21 of the mounting member 5 is oriented in a predetermined direction. As long as the mounting member 5 is attached to the top plate 4a,
Can be quickly and easily mounted by directing the mounting direction to a predetermined direction. That is, when the insertion portion 6 of the callan 1 is inserted into the cylindrical portion 5c of the mounting member 5 from above, the positioning projection 20 is positioned on the flange of the mounting member 5 at a position where the positioning projection 20 and the concave groove 21 do not match. In this state, the engaging portion 2 of the callan 1 and the detent engaging portion 3 of the mounting member 5 do not engage with each other, and the positioning projection 20 is made to slide on the flange 5a. Curran 1
Is rotated to insert the positioning projection 20 into the concave groove 21 so that the callan 1 falls down and the engaging portion 2 of the callan 1
And the detent engaging portion 3 of the mounting member 5 are engaged with each other, whereby the callan 1 is mounted on the mounting member 5 in a state where it is oriented in a predetermined direction. As long as it is installed at an accurate position, the installation of the callan 1 to be installed at the site can be easily performed without troublesome adjustment of the position without taking time.

When the insertion portion 6 of the callan 1 is inserted into the mounting member 5, the engaging member 8 is elastically engaged with the concave groove 7 provided in the insertion portion 6, and the callan 1 is prevented from coming off. FIGS. 4 and 5 show another embodiment. In this embodiment, the serrations 9 forming the engaging portions 2 provided on the caran 1 are provided with concave grooves 21 and provided on the mounting member. Serration 1 that forms a detent engagement portion
The positioning projections 20 are provided on the reference numeral 0, and also in this case, the callan 1 can be mounted in such a manner that it can be easily turned in a predetermined direction without any trouble even without finely adjusting the position.

FIG. 6 shows still another embodiment. In mounting the mounting member 5 in the mounting hole 12 by tightening the nut 13, the mounting member 5 does not rotate together with the nut 13. 12. As shown in FIG.
A pair of concave grooves 23 is formed in the outer peripheral surface of the cylindrical portion 5c along the longitudinal direction of the cylindrical portion 5c, and is shown in FIG. 9 from the inner peripheral edge of the seat plate 14 mounted on the cylindrical portion 5c. Groove 23 as
A locking projection 14a that is engaged with the projection is provided. Also,
Engagement claws 14b protrude upward from the outer peripheral edge of the seat plate 14 at predetermined intervals. When the mounting member 5 is mounted in the mounting hole 12, the seat plate 14 is mounted on the cylindrical portion 5c, and the nut 13 is screwed into the cylindrical portion 5c and tightened, as shown in FIG. The mounting member 5 is mounted in the mounting hole 12 by sandwiching the opening edge of the mounting hole 12 between the flange 5 a, the seat plate 14, and the nut 13, and the locking claw 14 b of the seat plate 14 is connected to the lower opening edge of the mounting hole 12. Before being brought into contact with the mounting member 5, the mounting member 5 is rotated in the mounting hole 12 so as to face a predetermined direction, and the nut 13 is tightened in this state. It is bite-pressed and locked, whereby the seat plate 14
Is prevented from rotating, and since the seat plate 14 and the cylindrical portion 5c are connected to each other by the engagement of the locking projections 14a with the concave grooves 23, the mounting member 5 is prevented from rotating. Even if the nut 13 is strongly tightened, the mounting member 5 does not rotate together with the nut 13,
The attachment member 5 can be quickly attached to the attachment hole 12 so that the attachment member 5 is oriented in a predetermined direction.
