In addition, the clearance Z between the boss portion 4 of the operating knob 3 and the hole 7 of the front plate 6 may be determined by the looseness of the cock shaft 2 itself, variations in screw attachment between the mounting bracket 8, the gas cock 1, and the middle plate 12,
Furthermore, the mounting needs to be made larger in consideration of dimensional variations of the metal fittings 8 themselves, variations in screw attachment of the front plate 6 to the middle plate 12, and the like.

Problems to be Solved by the Invention However, in the above configuration, the clearance Y and the clearance Z become large, resulting in a poor appearance and deteriorating the aesthetic appearance.In addition, there are other problems such as intrusion of boiling liquid during cooking. had.

In view of the above-mentioned problems, the present invention provides an apparatus for mounting an operating part of a gas cooker, etc., which makes the clearance between the operating knob and the front plate appear smaller, and maintains the aesthetic appearance.

Means for Solving the Problems In order to solve the above-mentioned problems, the device for attaching the operation part of a gas cooker, etc. of the present invention includes a front plate having a hole through which the cock shaft is inserted, and a hollow part through which the cock shaft is inserted. A decorative ring is moved in the radial direction, with an annular convex portion formed at the center protruding toward the front plate, and an annular concave portion facing the operating portion of the operating knob protruding toward the opposite side from the front plate at the outer periphery. It has a configuration that allows it to be provided.

The present invention has the above-described structure, so that even if the cock shaft itself rattles or the gas cock, mounting brackets, front plate, etc. The clearance between the convex part and the front plate absorbs variations and covers the clearance between the end face of the operating part of the operating knob and the front plate to maintain an aesthetic appearance.

EXAMPLE Hereinafter, a device for installing an operating part of a gas cooker according to an embodiment of the present invention will be described with reference to the drawings.

FIG. 1 shows a cross section of a main part of an operating section of a gas cooker according to an embodiment of the present invention, and FIG. 2 shows a partially enlarged view thereof.

1 and 2, 14 is a gas cock which has a cock shaft 15 and opens and closes the gas circuit; 16 is a boss portion 17 into which the tip of the cock shaft 16 is inserted; This is an operation knob having an operation section 18 for performing operations. Reference numeral 19 denotes a front plate which forms the main body of the device and has a hole 20 through which the cock shaft 15 is inserted, and is provided with indications such as operation methods. 21 is a hollow portion 2 through which the cock shaft 16 is inserted;
An annular convex portion 22 having a diameter of 2a protrudes from the center toward the front plate 19, and the convex portion 22 is inserted into the hole 2o and attached so as to be movable in the radial direction. This is a decorative ring in which an annular recess 23 facing the part 18 is protruded in the direction opposite to the front plate 19 at the outer peripheral part. Reference numeral 24 denotes a ring-shaped stopper, which is inserted into the convex portion 22 against elastic force and is attached to the convex portion 22. By applying the outer peripheral end to the back surface of the front plate 9, the inner end is attached to the convex portion 22 at a position deeper than the front plate 19.
