BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for pivotally supporting a swinging link for rotating a wind direction adjusting vane of a vehicle air-conditioning case on an air-conditioning case base.

[0002]

2. Description of the Related Art Pins projecting from the lower ends of a plurality of wind direction adjusting vanes axially supported by an air-conditioning case are pivotally attached to the tip of a rocking link, and the rear part of the rocking link is attached to the air-conditioning case base. In the case of supporting the shaft so that it cannot be pulled out from the stand, conventionally, rivets were inserted and heat caulking was performed.

[0003]

In the above-mentioned prior art, there is a problem that the workability is poor and the dimensional accuracy is poor because of heat caulking.

[0004]

SUMMARY OF THE INVENTION In order to solve the above problems, the present invention has a plurality of wind direction adjusting blades vertically supported by an air-conditioning case, each of which is provided with a pin projecting from the lower end of a swinging link. An air conditioner fitted in a split groove, the pin in the middle part of the swing link being fitted in the cam groove of the slide plate, and the rear part of the swing link being pivotally supported on the air conditioning case base. At this point, a split slit that passes through the axial center from the tip is formed, and a locking pin having an umbrella-shaped head and a locking step that is capable of elastically reducing and restoring the diameter is projected from the long board, It is characterized in that it is fitted into the pin hole of the base and the pin hole of the swing link and is rotatably locked.

[0005]

1 to 5 show a first embodiment of the present invention.
Reference numeral 1 is an air conditioning case, and the upper and lower ends of a plurality of wind direction adjusting blades 2 are provided on the upper surface 1a of the air conditioning case 1 and the upper surface of the base 1b.
It is rotatably supported by upper and lower rotating shafts 3 and 4.
Reference numeral 5 denotes a plurality of swing links arranged on the base 1b. The pin 6 at the lower end of the wind direction adjusting blade 2 is fitted into the split groove 5a at the tip of the swing link 5, and the lower surface of the middle portion of the swing link 5 is fitted. The cam groove 8 of the slide plate 8 that slides the pin 7 of the above along the lower surface of the base 1b.
It is fitted to a.

Reference numeral 9 is a member having two opposed slits 9a passing through the axial center from the tip and having an umbrella-shaped head 9b and a locking step 9c which are elastically capable of reducing or expanding the diameter. With a stop pin, protruding from the long board 10, the locking pin 9 is passed through the pin hole 1c of the base 1b and the pin hole 5b at the rear end of the swinging link 5 by its elasticity to reduce the diameter. After the penetration, the diameter is expanded to the original state, and the locking step 9c is rotatably locked to the upper surface of the swing link 5.

FIGS. 6 to 8 show a second embodiment of the present invention, in which a locking pin 9'is formed with three split slits 9a 'passing through the shaft center from the tip thereof, and the locking step 9c' is provided with a slit. -I am wearing a pad.

[0008]

According to the present invention, pins protruding from the lower ends of a plurality of wind direction adjusting vanes axially supported by the air-conditioning case are fitted in the split grooves at the tip of the swing link, respectively, and the swing link is attached. In an air conditioner in which the pin in the middle part is fitted in the cam groove of the slide plate and the rear part of the swing link is pivotally supported by the air conditioning case base, a split slit that passes from the tip to the axis center is provided. A locking pin having an umbrella-shaped head and a locking step that is formed so that the diameter can be elastically reduced and restored is projected from the long substrate, and the pin hole of the base and the pin hole of the swing link are formed. It has the following effects because it is fitted to and is rotatably locked.

1. When assembling, each pin is attached to the long board, so it can be done all at once, which reduces the number of work steps. 2. Since the diameter can be elastically reduced and expanded, some errors are absorbed and backlash does not occur.
