A fixed moment that corrects the inclination acts on the piece, and the front surface of the end piece can be prevented from being inclined in the front-rear direction with respect to the front surface of the operation panel.

  An insertion clearance exists between the inner surface of the female engagement portion and the outer surface of the male engagement portion, and the straight portion of the male engagement portion can be inclined by the insertion clearance in the female engagement portion. Here, if at least one of the outer surface of the stove body and the end piece is provided with a second urging portion that imparts a forward urging force to the end piece, the inner surface on the front side of the female engagement portion is provided. The straight portion of the male engaging portion is pressed by the urging force of the second urging means. Therefore, the inclination of the straight part within the female engagement part is prevented, and the inclination of the end piece is reliably corrected.

  By the way, the operation panel is made of sheet metal, and an end surface portion is formed by bending the metal plate at the lateral outer end of the operation panel, and a female engagement portion is formed by drilling such as a burring hole on this end surface portion. However, in this case, it is difficult to ensure the dimensional accuracy and position accuracy of the female engaging portion. On the other hand, the operation panel is composed of a metal extrusion molded product, a resin molded product, or a combination of a metal extrusion molded product and a resin molded product, and the female engagement portion is formed when the molded product constituting the operation panel is molded. If this is formed, the labor of processing the female engaging portion can be saved, and the dimensional accuracy and position accuracy of the female engaging portion can be secured, and the positioning accuracy of the end piece with respect to the operation panel is improved.

The end piece 9 is made of resin, and an aluminum plate 911 extending from the front surface to the upper and lower end surfaces is attached to the front portion 91 so that a sense of unity with the operation panel 6 made of an extruded aluminum material can be obtained. I have to. The rear half of the extension plate portion 92 is divided into a first tongue piece portion 93 at the center in the vertical direction and second tongue piece portions 94 and 94 above and below the first tongue piece portion 93. Each second tongue piece 94 extends rearward from the first tongue piece 93, and at its rear end, as shown in FIG. 4, the first and second upper and lower upper and lower two bulges inward in the lateral direction. Convex portions 941 and 942 are formed. The second convex portion 942 has a long hole 942a that is long in the vertical direction, and the rear edge of the long hole 942a remains as a thin beam portion 942b. A protrusion 942c protruding rearward is formed at the center of the rear edge of the beam portion 942b, and a weakening groove 942d is formed at the center of the front edge (the edge on the long hole 942a side) of the beam portion 942b.

  On the outer surface 1b of the stove main body 1, a fulcrum portion 1c formed of a bridge-like cut and raised portion corresponding to the first tongue piece portion 93 is formed. Then, as shown in FIG. 5, the first tongue piece 93 is inserted into the fulcrum 1 c from the front, and the end piece 9 is attached to the outer surface 1 b of the stove body 1. At this time, the first and second convex portions 941 and 942 abut against the outer surface 1b of the stove body 1, and the rear end portion of the second tongue piece portion 94 is pushed laterally outward. In this state, the first tongue piece 93 is pressed from the lateral direction outward by the fulcrum part 1c at a position in front of both the convex parts 941 and 942, so that the contact between the first tongue piece part 93 and the fulcrum part 1c is achieved.

The upper and lower male engaging portions 95U and 95L are fitted to the female engaging portions 65U and 65L. According to this, the front portion 91 of the end piece 9 is directly positioned with respect to the operation panel 6, and the positional displacement of the end piece 9 with respect to the operation panel 6 in the vertical direction and the front-rear direction is prevented. Further, the front portion 91 of the end piece 9 receives an urging force inward in the lateral direction provided by the first and second convex portions 941 and 942 at the rear end of the second tongue piece portion 94 and receives an operation panel. 6 is closely attached to the lateral outer end surface, and a gap is prevented from being generated between the operation panel 6 and the end piece 9. The front edge side portion of the outer surface 1b of the stove body 1 is recessed inwardly from the lateral outer end surface of the operation panel 6, and the front portion 91 of the end piece 9 interferes with the outer surface 1b of the stove body 1. It is possible to prevent contact with the lateral outer end surface of the operation panel 9 from becoming impossible.

  By the way, when the end piece 9 is attached, the lateral inner surface of the end piece 9 is separated from the lateral outer end surface of the operation panel 6 by at least the protruding height of the male engagement portions 95U and 95L. It is necessary to fit the engaging portions 95U and 95L to the female engaging portions 65U and 65L. After the end piece 9 is attached, the end piece 9 is placed between the lateral outer side surface and the side surface of the stove installation space. At least a gap corresponding to the protruding height of the male engagement portions 95U and 95L is opened. In order to narrow this gap, the protruding height of each male engaging portion 95U, 95L is relatively small, for example, set to about 2 to 3 mm. A straight portion 95a having a length of about 1 to 1.5 mm, which is straight in the lateral direction, is formed at the base end portion of each male engagement portion 95U, 95L. The female engaging portions 65U and 65L are formed at the time of forming an aluminum extruded product constituting the operation panel 6, and extend over the entire lateral length of the operation panel 6. Therefore, the recessed depth of each of the female engaging portions 65U and 65L with respect to the lateral outer end surface of the operation panel 6 is, of course, the respective male engaging portions 95U and 95L with respect to the lateral inner surface of the end piece 9. The straight engagement portions 95a of the male engagement portions 95U and 95L are fitted over the entire length of the female engagement portions 65U and 65L.

  Here, when the operation panel 6 is displaced laterally with respect to the stove body 1, the end piece 9 is inclined in the lateral direction in the front-rear direction, and the front surface of the end piece 9 is inclined in the front-rear direction with respect to the front surface of the operation panel 6. There is a possibility. However, in the present embodiment, a fixing moment that corrects the inclination acts on the end piece 9 by the straight portions 95a of the male engaging portions 95U and 95L fitted to the female engaging portions 65U and 65L. As a result, the lateral displacement of the operation panel 6 with respect to the stove body 1 is absorbed by the bending of the extension plate portion 92 (tongue piece portions 93 and 94) of the end piece 9, and the end piece 9 with respect to the front surface of the operation panel 6 is absorbed. It is possible to prevent the front surface of the camera from being inclined in the front-rear direction.

  However, there is an insertion clearance between the inner surfaces of the female engaging portions 65U and 65L and the outer surfaces of the male engaging portions 95U and 95L, and the straight portions 95a of the male engaging portions 95U and 95L are female engaging members. The joints 65U and 65L can be tilted by the insertion clearance. Here, in the present embodiment, the female engagement portions 65U and 65L are in a state where the beam portion 942b is forcibly bent by the contact of the beam portion 942b with the stopper portion 1d of the outer surface 1b of the stove body 1. The male engaging portions 95U and 95L are fitted into the first and second engaging portions. Therefore, due to the forward biasing force applied to the end piece 9 by the bending reaction force of the beam portion 942b, the straight portions 95a of the male engagement portions 95U and 95L are formed on the front inner surfaces of the female engagement portions 65U and 65L. Press contact. As a result, the inclination of the straight portion 95a in the female engagement portions 65U and 65L is prevented, and the inclination of the end piece 9 is reliably corrected. Further, the end piece 9 is also prevented from being displaced in the front-rear direction by the amount of the insertion clearance, and the flushness between the front surface of the operation panel 6 and the front surface of the end piece 9 is ensured with high accuracy.

  In the present embodiment, as described above, the female engaging portions 65U and 65L are formed when an aluminum extrusion-molded product serving as the operation panel 6 is formed. Therefore, it is possible to save the labor of processing the female engaging portions 65U and 65L, and also to ensure the dimensional accuracy and positional accuracy of the female engaging portions 65U and 65L, and the positioning accuracy of the end piece 9 with respect to the operation panel 6 Will improve.

  Furthermore, in this embodiment, the end piece 9 is formed in a vertically symmetrical shape. Therefore, by inverting the same end piece 9 up and down, the same end piece 9 can be attached to either the left or right outer surface 1b of the stove main body 1, and the cost can be reduced by sharing parts. The upper female engagement portion 65U of the operation panel 6 is formed in a square groove shape, while the lower female engagement portion 65L is formed in a round hole shape. The male engaging portions 95U and 95L are both formed in a pin shape with a circular cross section so that the male engaging portions 95U and 95L can be fitted to any of the upper and lower female engaging portions 65U and 65L. When the end piece 9 is manufactured separately on the left and right sides, it is desirable that the upper male engagement portion 95U be formed in a square cross section in accordance with the upper female engagement portion 65L.

  In the above embodiment, the operation panel 6 is made of an extruded product of aluminum. However, the operation panel can be made of a resin molded product, and further, as shown in FIG. 7, an extruded product of aluminum. It is also possible to configure the operation panel 6 by combining the upper half 6a constituted by the above and the lower half 6b constituted by a resin molded product. In this case, the upper female engaging portion 65U is formed at the time of molding the extruded product of aluminum that becomes the upper half 6a, and the pin that is set in the molding die at the time of molding the resin molded product that becomes the lower half 6b. A lower female engagement portion 65L is formed. According to this, similarly to the above-described embodiment, it is possible to save the labor of processing the female engaging portions 65U and 65L, and also to ensure the dimensional accuracy and position accuracy of the female engaging portions 65U and 65L, The positioning accuracy of the end piece 9 with respect to the operation panel 6 is improved. In the case shown in FIG. 7, the storage box 81 of the control panel 8 is integrally formed with the lower half 6b.
