In this state, the tip of each engagement plate substantially coincides with the outer edge of the outermost exhaust port 21.
By sliding and rotating the engagement plate 50, the peripheral edge of the exhaust port 21 is inserted into the engagement recess 53, and the engagement plate 50 is fixed again with screws. As a result, the plate-shaped main body 40 of the exhaust guide plate 4 is fixedly engaged at a position facing the exhaust ports 21, 21 of the instrument A via the tongue piece 61 and the engagement plate 50 at both ends thereof.

In this locked and fixed state, the exhaust port 21 is only blocked by a portion of the flat plate-shaped engagement plate 50.

Note that although the distance between the outer edges of the outermost exhaust ports 21 and 21 and the engagement recess 53 of the engagement plate 50 does not necessarily match, since the screwed part of the engagement plate 50 is the long hole 51, The mounting position of the engagement plate 50 can be adjusted within this range.

[Effects] Since the present invention has the above configuration, it has the following unique effects.

When the exhaust guide plate 4 is attached to the exhaust port 21 of the appliance A, the area in which the exhaust port 21 is blocked becomes extremely small, so that fuel defects caused by attaching the exhaust guide plate 4 can be eliminated.

Also, an engagement plate 5 for engaging the exhaust guide plate 4.
0 is the outermost exhaust port 21, 21 to be engaged
Since it can be adjusted according to the outer edge spacing of the outer edge, it can be used even with different spacings.

[Example] Hereinafter, an example of the present invention will be described based on FIGS. 1 to 4.

Apparatus A to which the exhaust guide plate 4 of the present invention is attached has a configuration as shown in FIG. The main box 1 and the cover plate 2 are screwed to each other at the open ends and integrated. A plurality of exhaust ports 21 are formed on the top surface of the exhaust top slightly protruding from the surface of the cover plate 2.

In this embodiment, as shown in FIG. As shown in FIG. 3, the cross-sectional shape is a dogleg shape that projects diagonally downward, and extension tongues 60 project from both ends of the plate-shaped main body 40. The protruding side edge (upright side) of this extension tongue piece 60 is continuous with the lower edge of the plate-shaped main body 40, and these three edges constitute one plane. Further, on the inner surface of the extension tongue piece 60, a tongue piece 61 that projects inward is arranged as shown in FIGS. 1 and 3, and a hook-shaped engagement plate 50 is screwed to this tongue piece 61. has been done.

The engagement plate 50 has a long hole 51 formed at its base end, and is screwed to the tongue piece 61 by a screw 52 passing through the long hole 51. Therefore, when the screw 52 is loosened, the engagement plate 50 is rotatable about the screw 52 and slidable in the direction of the elongated hole 51 . Further, in this engagement plate 50, an engagement recess 53 is formed outward, and a distance from the elongated hole 51 to the engagement recess 53 is set to a predetermined value.
When engaged, both the lower edge of the plate-shaped main body 40 and the tip of the extension tongue piece 60 are opposed to the surface of the lid plate 2.

Therefore, in this embodiment, with each screw 52 loosened, the engagement plate 50 is made swingable as shown in FIG.
