2. Description of the Related Art As a technique of this kind, for example, as shown in FIGS. 4 to 6 (see JP-A-64-12909), 1 is a hot water pipe case, 2 is the hot water pipe case 1
A valve 3 disposed inside is a valve shaft rotatably supporting the valve 2, 4 is a lever having one end 4a coupled to the valve shaft 3, and a lever 5 for rotating the valve shaft 3 It is an operating means for urging the turning force to the other end 4b of the lever 4 in the direction of closing the valve 2. The operating means 5 includes a link 7 formed with a notch 6 for engaging the other end 4b of the lever 4 and an outer wire 9a supported by a vehicle body 8 and the inner wire 9b is connected to a boss 7a of the link 7. It is composed of a cable 9 that has been connected. Reference numeral 10 is a link bracket that supports the link 7 on the hot water pipe case 1.
Reference numeral 11 denotes a coil spring wound around one end 4a of the lever 4, the one end 11a of which is engaged with the link 7 and the other end 11b of which is engaged with the lever 4. Therefore, by constantly rotating the lever 4 in the clockwise direction by the urging force of the coil spring 11,
Is in the “open” state in the hot water pipe case 1. Next, the other end of the inner wire 9b of the cable 9 (not shown)
By urging the coil spring 11 in the pulling direction,
By rotating the lever 4 counterclockwise against the urging force of the valve 2, the valve 2 is closed in the hot water pipe case 1.

[0003]

However, according to such a structure, the overall height from the hot water pipe case 1 to the lever 4 becomes high, and the layout is restricted. Therefore, an object of the present invention is to provide an automobile air conditioner in which the height of the valve control means of the hot water pipe case can be lowered to ensure the freedom of layout.

[0004]

As an air conditioner for an automobile according to the present invention, a valve provided in a hot water pipe case, a valve shaft rotatably supporting the valve, and one end of the valve shaft are provided. A lever that is connected to rotate the valve shaft, and an operating means that applies rotational force to the other end of the lever in the direction to close the valve, the lever being one end of the lever. From a leaf spring connected to the other end,
The lever includes the first guide projecting from the one end to the other end via the leaf spring and the second guide projecting from the other end of the lever to the one end. A predetermined gap is formed between the opposing first ends of the first guide and the second guide on the side to which the biasing force is applied to,
It is characterized in that the first guide and the second guide on the opposite side to the side on which the biasing force is applied to the lever by the operating means are formed in contact with each other between the opposing second end portions.

[0005]

[Operation] According to the present invention, since the structure for applying the prescribed sealing pressure to the sealing portion at the valve closed position is a small number of components and the overall structure is low, it is possible to provide an adjusting device that is not restricted by layout. .

[0006]

Embodiments of the present invention will now be described in detail with reference to the drawings. The same or equivalent means as those of the conventional example will be denoted by the same reference numerals, and overlapping description will be omitted. 1 to 3 show an embodiment of the present invention, 1 is a hot water pipe case, 2 is a valve disposed in the hot water pipe case 1, and 3 is a valve shaft rotatably supporting the valve 2. , 13 are levers whose one end 13a is coupled to the valve shaft 3 so as to rotate the valve shaft 3, and 14 is the lever 13 for closing the valve 2.
Is an operating means for urging the turning force to the other end portion 13b of the. The operating means 14 comprises a cable 9 connected to the boss 14a of the other end 13b of the lever 13,
The outer wire 9a is supported by the vehicle body 8 and the inner wire 9b is connected to the boss 14a. The lever 13 includes a leaf spring 15 connected from one end portion 13a of the lever 13 to the other end portion 13b, and a first guide protruding from the one end portion 13a side to the other end portion 13b side through the leaf spring 15. 16 and a second guide 17 protruding from the other end 13b side of the lever 13 to the one end 13a side, and a first guide 16 and a second guide 16 on the side where the lever 13 is biased by the operating means 14. A predetermined interval is formed between the opposed first ends 18 and 19 of the guide 17, and the first guide 16 and the second guide on the side opposite to the side on which the lever 13 is biased by the operating means 14. It is formed by abutting between the opposed second end portions 20 and 21 of 17.

Therefore, as shown in FIG. 2, the valve 2 is opened in the hot water pipe case 1 by rotating the lever 13 clockwise by the urging force of the leaf spring 15. At this time, a predetermined gap is formed between the first end portions 18 and 19, and the second end portions 20 and 21 are in contact with each other. Next, as shown in FIG. 3, by urging the other end (not shown) of the inner wire 9b of the cable 9 in a pulling direction, the first ends 18 and 19 come close to each other, and The second end portions 20 and 21 are held in a separated state. In this state, the valve 2 is “closed” in the hot water pipe case 1, and the valve 2
In the closed position of, the specified sealing pressure is applied to the seal portion (not shown). Since such a structure is composed of a small number of constituent parts and has a low height as a whole, it is possible to provide an adjusting device which is not restricted by layout.

[0008]

As described above, the air conditioner for an automobile according to the present invention includes a valve disposed in a hot water pipe case, a valve shaft rotatably supporting the valve, and one end of the valve shaft. A lever that is connected to rotate the valve shaft, and an operating means that applies rotational force to the other end of the lever in the direction to close the valve, the lever being one end of the lever. From a leaf spring connected to the other end,
The lever includes the first guide projecting from the one end to the other end via the leaf spring and the second guide projecting from the other end of the lever to the one end. A predetermined gap is formed between the opposing first ends of the first guide and the second guide on the side to which the biasing force is applied to,
Since the first guide and the second guide on the opposite side to the side on which the biasing force is applied to the lever by the operating means are formed in contact with each other, the opposing second end portions of the first guide and the second guide are in contact with each other. There is a practical effect that the adjusting device can be a structure free from layout restrictions because the structure has a small number of structural parts that apply a prescribed sealing pressure to the seal portion at the closed position and has a low overall structure.
