[Prior Art]

 When a device such as a gas stove is installed in a space, a gap may occur between the space and the outer surface of the device. For example, in the case of a drop-in stove, a flange is projected from the upper peripheral edge of the stove, and the stove is fitted into the opening provided in the top plate from above, and the stove is suspended on the top plate by a flange. In this case, the stove body must pass through the opening from top to bottom, so that the stove is formed with a width smaller than the width of the installation space provided on the lower side of the top plate to facilitate storage. In the installed state, there will be a gap between both sides of the stove and the inner surface of the installation space. If this condition is left, the external appearance will be impaired, so the stove is attached to the gap before the end piece is attached. As a mechanism for attaching this end piece, a plate-shaped spring is screwed to the outer surface of the device in advance, and the end piece with a U-shaped cross section is inserted into the gap with the U-shaped opening surface facing backward. The one in which one side wall of the end piece is elastically sandwiched between the plate-shaped spring and the outer surface of the device is described in Japanese Utility Model Publication No. 1-154844.

Is suspended by engaging the top plate 11. The stove 1 inserted from the opening 12 is stored in the installation space 2 provided below the top plate 11. By the way, the width of the stove 1 is formed to be narrower than the frontage of the installation space 2. Therefore, when the stove 1 is housed in the installation space 2, there is a gap between both inner side walls 21 of the installation space 2 and both outer side surfaces 3 of the stove 1. Occurs. To cover this gap, the stove 1 is housed in the installation space 2 and then the end pieces 4 are inserted into the gap from the front.

The end piece 4 is made of a synthetic resin material, and as shown in FIG. 3, a joint surface 40 in contact with the outer surface 3 of the stove 1 is extended forward in the insertion direction, and is inserted in the joint surface 40 in the insertion direction. By providing the four notches along the first tongue piece 41, the first tongue piece 41 is formed in the central portion, the second tongue pieces 43 are formed on both upper and lower sides of the first tongue piece 41, and the third tongue piece 401 is further formed on the upper and lower sides. Has been done. The tip of the first tongue piece 41 is provided with an inclined portion 42 located on the opposite surface of the joint surface 40, and the tip of the second tongue piece 43 is located on the joint surface 40 side. An extremely high holding convex portion 44 and a relatively low biasing convex portion 45 are provided respectively. On the other hand, the first tongue piece 41 is inserted into the outer side surface 3 of the stove 1, and the bridge-shaped fulcrum portion 31 that presses the first tongue piece 41 toward the outer side surface 3 side and the end piece 4 is inserted into the above-mentioned gap and the outside The holding convex portion 44 is fitted in the state of being attached to the side surface 3, and the holding hole 32 for holding the posture of the end piece 4 is provided. A sloping portion 31a for facilitating the insertion of the first tongue piece 41 into the fulcrum portion 31 is formed at the front mouth of the fulcrum portion 31.

According to the above configuration, when the end piece 4 is inserted into the gap formed between the inner wall 21 of the installation space 2 and the outer surface 3 of the stove 1, the second tongue piece 43 is provided at the tip. Since it is lifted by the holding convex portion 44, the second tongue piece 43 is elastically deformed and the first tongue piece 41 is pressed against the outer surface 3 side, while the inclined portion 42 of the first tongue piece 41 and the inclination of the fulcrum portion 31 are inclined. The first tongue piece 41 is guided into the fulcrum portion 31 by engaging with the portion 31a. When the end piece 4 is further inserted to the fixed position, the holding projection 44 of the second tongue piece 43 is fitted into the holding hole 32 which is located in front of the fulcrum portion 31 in the insertion direction, and the end piece 4 is further removed. Therefore, the end piece 4 is held in the fixed position. Since the second tongue piece 43 is provided with the biasing convex portion 45, the tip of the second tongue piece 43 is lifted from the outer side surface 3 and the first tongue piece 41 is pressed against the fulcrum portion 31. Then, the end piece 4 is pressed toward the outer surface 3 by the fulcrum portion 31, and the second tongue piece 43 is elastically deformed by the biasing convex portion 45. The elastic force due to this elastic deformation acts on the contact portion between the fulcrum portion 31 and the first tongue piece 41 as a fulcrum in the insertion direction tail end portion of the end piece 4, that is, in the direction in which the front end portion is pressed against the outer surface 3. To do. Therefore, the end piece 4 is stably held by the frictional force acting between the end piece 4 and the outer side surface 3, and the front end portion of the end piece 4 and the outer side surface 3 do not have a gap between them, and the outer appearance is improved. Is not damaged.

By the way, as shown in FIG. 5, the holding convex portion 44 is provided with an inclined surface 44a that facilitates the holding convex portion 44 from coming out of the holding hole 32 when the end piece 4 is removed. A vertical wall 44b is provided in the inner wall of the holding hole 32 so that the vertical wall 44b abuts against the inner peripheral edge of the holding hole 32 so that the end piece 4 is not pushed further from the fixed position. The end piece shown in Fig. 3 shows the posture when it is inserted into the left gap, and when inserting it into the right gap, the same shape is used upside down.

In the above embodiment, the holding projection 44 is provided on the side of the end piece 4 and the holding hole 32 is provided on the side of the stove 1. However, conversely, a hole for holding is provided on the side of the end piece 4 and the holding hole is provided on the side of the stove 1.
