As shown in FIG. 3, the fixture 42 is formed in a substantially U-shape, and is composed of a first portion 42A, a second portion 42B, and a third portion 42C. The first portion 42A is a portion fixed to the front surface of the flow rate adjusting portion 31, and is formed so as to extend to the left and right at the time of fixing. As shown in FIG. 3, in the first portion 42A, two insertion holes 42D and a first hole 42E are formed at positions facing the protrusion 31A and the screw hole 31B of the flow rate adjusting unit 31, respectively. The second portion 42B is formed so as to extend forward from the left end portion of the first portion 42A. The third portion 42C is formed so as to extend to the right from the front end portion of the second portion 42B. As shown in FIG. 3, the third portion 42C has a protrusion 42F formed by vertically bending the right tip portion forward, and a second hole 42G formed substantially in the center of the third portion 42C in the left-right direction. .. As shown in FIG. 3, the fixture 42 has flange portions 42H formed above and below a part of the second portion 42B and the first portion 42A, respectively. Thereby, the strength of the fixture 42 can be strengthened.

With reference to FIG. 4, a method of fixing the fixture 42 to the flow rate adjusting unit 31 (fuel supply device 20) will be described. In the fixture 42, the protrusion 31A of the flow rate adjusting portion 31 is inserted into the insertion hole 42D, and the fixture is positioned. Then, the fixture 42 and the flow rate adjusting portion 31 are fixed by inserting screws 50 for co-tightening into the first hole 42E of the fixing tool 42 and the screw hole 31B of the flow rate adjusting portion 31, respectively. The reason for screwing with the co-tightening screw is to prevent the screw from loosening.

The hole 2C is formed. Since the two fuel supply devices 20 are fixed to each front frame 2A by the fixture 42, two slits 2B and two screw holes 2C are formed.

The panel device 51 will be described with reference to FIG. FIG. 6 is a diagram in which the panel device 51 is mounted on the front frame 2A on the left side. As shown in FIG. 6, the panel device 51 is formed with screw holes 51A at both ends of the upper front surface. The screw hole 51A is formed at a position facing the screw hole 2C of the front frame 2A on the left side. Further, as shown in FIG. 6, the panel device 51 is formed with two through holes 51B for inserting the operation knobs 13 and 14. Therefore, with the operation knobs 13 and 14 inserted into the through holes 51B, the panel device 51, the front frame 2A, and the fixing tool 42 can be fixed to the housing 2 by screwing them with screws for co-tightening. .. The reason for screwing with the co-tightening screw is to prevent the screw from loosening. Further, the protrusion 42F is inserted into the slit 2B for positioning, and the axial center AX of the operation knobs 13 and 14 penetrates in a state where the second hole 42G, the screw hole 2C, and the screw hole 51A are screwed and fixed. The positions of the protrusion 42F, the slit 2B, the second hole 42G, the screw hole 2C, and the screw hole 51A are determined so as to coincide with the center of the hole 51B.

The decorative panel 52 will be described with reference to FIG. 7. As shown in FIG. 7, the decorative panel 52 is formed with a through hole 52A having the same shape as the cross section perpendicular to the front-rear direction of the operation knobs 13 and 14.

A tubular member 52B provided in the through hole 52A of the decorative panel 52 will be described with reference to FIGS. 8 and 9. FIG. 8 is an exploded view of the decorative panel 52, the tubular member 52B, and the panel device 51. As shown in FIGS. 8 and 9, the through hole 52A has a tubular member 52B slidable along the rear surface of the decorative panel 52 at the rear end portion in the through hole 52A. The outer diameter of the tubular member 52B is formed to be smaller than the diameter of the through hole 51B of the panel device 51, and the rear end portion of the tubular member 52B is inserted into the through hole 51B. As shown in FIGS. 8 and 9, the tubular member 52B has a flange portion 52B1 having a circular outer peripheral shape, which extends in a direction away from the outer peripheral portion of the front end portion. The flange portion 52B1 is formed in a shape in which the tip portion is bent forward, that is, in an L shape. Further, the outer diameter of the flange portion 52B1 is formed to be larger than the diameter of the through hole 51B. As shown in FIG. 9, the flange portion 52B1 is inserted in the space between the panel device 51 and the decorative panel 52. As described above, the rear end portion of the tubular member 52B is inserted into the through hole 51B, the outer diameter of the tubular member 52B is smaller than the diameter of the through hole 51B, and the outer diameter of the flange portion 52B1 is smaller than the diameter of the through hole 51B. big. Therefore, the tubular member 52B becomes slidable along the surface of the decorative panel 52 at the rear end portion in the through hole 52A.

In this way, the tubular member 52B having the slidable flange portion 52A1 is inserted into the through hole 52A, and by inserting the operation knob 13 into the tubular member 52B, when viewed from the front surface of the decorative panel 52. , The misalignment of the operation knob 13 can be made inconspicuous. Such a tubular member 52B is further inserted into the through hole 52A by inserting the protrusion 42F into the slit 2B for each gas stove 1 and positioning the second hole 42G, the screw hole 2C, and the screw hole 51A. 42F, slit 2B, second hole 42G, screw hole 2C, screw hole 51A so that the axial center AX of the operation knobs 13 and 14 coincides with the center of the through hole 51B. This is because it is difficult to determine the position of. That is, depending on the gas stove 1, when the protrusion 42F is inserted into the slit 2B for positioning and the second hole 42G, the screw hole 2C, and the screw hole 51A are screwed and fixed, the axial center of the operation knob 13 is used. The center of the AX and the through hole 52A may be misaligned. When the deviation occurs, the tubular member 52B fills the gap and the deviation can be made inconspicuous, so that the aesthetic appearance can be prevented from being spoiled.

According to the above embodiment, the gas stove 1 has a housing 2 and an operation knob 13 that can be pushed in and can rotate freely in the pushing direction, and the operation knob 13 protrudes from the inside of the housing to the front surface. A fuel supply device 20 arranged in a state is provided. The gas stove 1 has a through hole 51B, and includes a panel device 51 fixed to the front surface of the housing 2 with the operation knob 13 inserted into the through hole 51B. The gas stove 1 has a through hole 52A having the same shape as the cross-sectional shape of the operation knob 13 in the rotation direction, and the decorative panel 52 mounted on the front surface of the panel device 51 with the operation knob 13 inserted into the through hole 52A. To prepare for. The gas stove 1 has a fixture 42 that connects the fuel supply device 20 and the panel device 51. Since the fuel supply device 20 is fixed to the panel device 51 to which the decorative panel 52 is attached by the fixture 42, it is possible to prevent the operation knob 13 from being displaced. Therefore, it is possible to provide the gas stove 1 that does not spoil the aesthetic appearance.
