Further, as shown in FIGS. 8A and 8B, the four bolts 7 used for connecting the fixing plate 30 and the holder 20 are connected to the screw holes 25b and 25b of the right flange portion 25 of the holder 20 and the left flange portion 26. It is locked to the holder 20 in a state of being screwed into the screw holes 26b and 26b of.

Next, in order to support the holder 20 on the bracket 10, the upper and lower engaging pieces 24 of the left side plate 22L of the holder 20 are respectively placed in the upper and lower engaging piece insertion openings 12b of the connecting plate portion 12 of the bracket 10 from the front. Through, each engaging plate portion 24a is inserted into each guide groove 13a of the support plate portion 13.
Since the left side plate 22L side is engaged with the bracket 10, the position of the gas plug 3 is shifted to the left in the holder 20.

The holder 20 holding the gas plug 3 is moved rearward, and as shown in FIG. 8A, the plug portion 3b of the gas plug 3 is positioned behind the front end surface of the stud 2a. In the present embodiment, the bottom plate 21 of the holder 20 is brought into contact with the stopper plate portion 14 of the bracket 10.
