The support space V of the air conditioning pipe 1 is formed between the locking body 4 and the support portion 5 so as to be swingably connected to each other.

The locking body 4 has a main body portion 4a facing the support space V, and a pair of flange portions 4b which are respectively bent from opposite upper and lower ends of the main body portion 4a in the opposite direction to the support space V, 4c and 4c. The pair of flange portions 4b and 4c have directions in which openings are opposite to each other (the main body portion 4
The engaging recess 3 is formed so as to face the width direction of a), and the inner peripheral portion of the inner part of the engaging recess 3 is fitted to the screw portion 2a formed on the outer peripheral portion of the hanging bolt 2. A protruding portion (an example of the locking portion K) 3a formed by being sharpened so as to fit is provided. Therefore, the locking body 4 is displaced along the longitudinal direction of the hanging bolt 2 by inserting the hanging bolt 2 into the engaging recess 3 from the opening and fitting the threaded portion 2a and the protruding portion 3a into each other. Can be prevented. In order to smoothly engage the locking body 4 with the suspension bolt 2, the flange portions 4b and 4c are formed so that the projecting portion 3a follows the spiral shape of the screw portion 2a. It is formed so as to be inclined with respect to 4a. A mounting hole 7 for swingably mounting the supporting portion 5 is provided at the lower flange portion 4c and the lower end portion of the main body portion 4a. On the other hand, at the upper end of the main body 4b, there is provided an engaged hole 8 for engaging and fixing the swinging front end (the engaging portion 11 described later) of the supporting portion 5. This engaged hole 8 has a square "U"
The receiving portion 8a ("U" -shaped bottom portion) formed in a wide shape to receive the engaging portion 11 and the receiving engaging portion 11 is engaged. And a retaining portion 8b which prevents the hole 8 from coming off. Further, on the surface portion of the main body portion 4a opposite to the support space V, the suspension bolt 2 engaged in the locking recess 3 is pressed and biased toward the protruding portion 3a, and the pressing bias is applied. A leaf spring 9, which is an example of a biasing means capable of maintaining the locked state in which the protrusion 3a is locked by the suspension bolt 2 and does not move up and down, is attached. As shown in FIG. 1, the leaf spring 9 is provided at its base end with a fixing portion 9a to the main body portion 4a,
A notch portion 9b (an example of a locking portion K) that can be locked while being in contact with the suspension bolt 2 is provided at the tip portion, and a leaf spring 9 is biased toward the suspension bolt 2 at a side edge portion. A releasing operation portion (an example of an engagement releasing means) 9c used when releasing the engagement state by elastically deforming in the opposite direction is provided.

The mounting of the support fitting V on the suspension bolt 2 is
The engaging recesses 3 formed separately on the upper and lower flanges 4b and 4c are arranged so as to face the circumferential surfaces of the hanging bolts 2 in opposite directions, and the hanging bolts 2 extend from the engaging recesses 3 respectively.
By rotating the locking body 4 around the horizontal axis in the direction in which the suspension bolts are engaged, the suspension bolts 2 engaged in the engagement recesses 3 are urged by the leaf springs 9 toward the protrusion 3a. Then, it can be attached in a state where the locked state is maintained (see FIG. 3).

The supporting portion 5 is, as shown in FIGS.
It is formed in a curved band shape by a metal plate, and a hook portion 9 for the mounting hole 7 is provided at one end thereof, and the hook portion 9 is hooked in the mounting hole 7 and bent so as not to come off. As a result, it is swingably attached to the locking body 4. Further, at the other end of the support portion 5, there is provided an engaging portion 11 which can be engaged with the engaged hole 8 of the locking body 4. The engaging portion 11 is configured to include a projecting piece portion 11a extending along the longitudinal direction of the support portion 5 and an engaging hole 11b formed at a base end portion of the projecting piece portion 11a. The projecting piece portion 11a and the engaging hole 11b are formed in the receiving portion 8a and the retaining portion 8b of the engaged hole 8 with dimension settings corresponding respectively. Further, the projecting piece portion 11a is formed by being slightly bent inward of the curve with respect to the support portion 5 (see FIG. 1). Furthermore, the length dimension of the projecting piece portion 11a is as follows when the engaging portion 11 is engaged with the engaged hole 8.
It is set so that the tip end of the projecting piece 11a protrudes on the locus of movement of the hanging bolt 2 in the engagement recess 3 formed in the upper flange 4b. The suspension bolt 2 is prevented from coming off (see FIG. 6). The procedure of engaging the engaging portion 11 with the engaged hole 8 will be described. As the projecting piece portion 11a enters the receiving portion 8a, the bent slope portion of the protruding portion portion 11a abuts the retaining portion 8b and moves downward. The support portion 5 itself is elastically deformed in the diameter reducing direction. Then, when the projecting piece portion 11a is advanced until the retaining portion 8b faces the engagement hole 11b, the elastic restoring force acting on the support portion 5 causes the support portion 5 itself to expand in the radial direction. While being restored, the retaining portion 8b and the engaging hole 11b are in a fitted state, and the engagement between the engaged hole 8 and the engaging portion 11 is completed. This engagement state can be stably maintained because the elastic restoring force of the support portion 5 acts.

In this way, when the air-conditioning pipe 1 is attached to the suspension bolt 2 by the support bracket R (or only the support bracket R is attached to the suspension bolt 2), the vertical mounting position with respect to the suspension bolt 2 is changed. As shown in FIGS. 2B and 4, the release operation portion 9c is operated to approach the main body portion 4a side so that the protruding portion 3a and the cutout portion 9b to the suspension bolt 2 are formed.
The supporting metal fitting R can be slid to a predetermined upper and lower position by releasing the locked state, and the locked state at the moved position can be maintained by releasing the releasing operation portion 9c. (See FIG. 2C).
