Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a damper device for adjusting the air flow rate of a vehicle air conditioner.

(Prior Art) Conventionally, as a damper device of a vehicle air conditioner, as shown in FIG. 3, a slit d is provided at a left and right position near a shaft center of a damper substrate c having a support shaft a and a rotation shaft b on both left and right sides. The damper substrate c is provided with a projecting body e on the front side of the upper half and a projecting body e ′ on the back side of the lower half, which is a soft sealing material f having a larger area than the damper substrate c. As shown in FIG. 4 and FIG. 5, the division slit h is formed by forming holes g and g ′ at positions corresponding to e ′ and providing a division slit h in the center.
The upper half part f ₁ is arranged above the slit d of the damper substrate on the front side, and the lower half part f ₂ is arranged below the slit d of the damper substrate on the lower back side, and the projections e and e ′ are formed in the respective holes. Some are fitted with g and g'and fixed with an adhesive.

(Problems to be Solved by the Invention) In the above-mentioned prior art, the split slit of the soft sealing material is pulled laterally to be expanded, and the split slit is inserted into the slits on both sides of the damper substrate. Since it is stopped, there is a problem in that the length protruding from the outer periphery of the damper substrate is varied, and an excessively extended portion is rubbed against the vent case when the damper is rotated, which causes abnormal noise. Also, if there is a molding error in the size of the hole of the split slit and the size of the protrusion of the damper substrate, accurate positioning cannot be performed, and the protruding length of the soft seal material protruding from the outer periphery of the damper varies and the same as above. There was a problem that abnormal noise was generated.

(Means for Solving the Problem) The present invention has an object to solve the above-mentioned problems, and has a size of protruding a predetermined length outward from the outer periphery of a rectangular damper substrate having a support shaft and a rotation shaft on both sides. The rectangular flange-shaped soft seal material is divided into two along the axial center to form two U-shaped seal pieces, and the U-shaped rib pieces formed along the inner surface of the seal pieces are mounted on the damper substrate. It is characterized in that it is provided so as to project at predetermined positions on the front side of the half section and the back side of the lower half section, and the sealing pieces are arranged along the rib pieces and fixed to the damper substrate by adhesion.

(Operation) By disposing and fixing the U-shaped seal piece along the U-shaped rib projecting on the damper board, the seal piece is made to protrude from the outside of the damper board by a predetermined length so that the seal piece acts as a vent case. It abuts lightly to prevent abnormal noise when rotating.

(Embodiment) FIGS. 1 and 2 show an embodiment of the present invention. Reference numeral 1 is a rectangular damper substrate having a support shaft 3 and a rotation shaft 2 in the center of both sides. Numerals 4 and 4 ′ are seal pieces formed by dividing a quadrangular flange-shaped soft seal material having a size protruding outward from the outer periphery of the damper substrate 1 into two along the axial center. 5,5 ′
Is a U-shaped rib piece formed along the inner side surfaces of the seal pieces 4 and 4 ', and is projectingly fixed at a predetermined position on the upper front side and the lower back side of the damper substrate 1. The seal pieces 4, 4'are arranged along the rib pieces 5, 5'and fixed to the damper substrate 1.

(Effect) According to the present invention, a rectangular flange-shaped soft sealing material of a size protruding outward from the outer periphery of a rectangular damper substrate having a support shaft and a rotating shaft on both sides is divided into two along the center of the shaft. To form two U-shaped seal pieces, and U-shaped rib pieces formed along the inner side surface of the seal pieces are provided at predetermined positions on the front side and the back side of the lower half of the damper substrate. Since the seal piece is arranged along the rib piece and fixedly adhered to the damper board, the seal piece is arranged and fixed along the rib piece without pulling the seal piece. The length of the protruding seal piece can be made accurate, and the seal piece can be lightly abutted and rotated on the vent case to prevent the generation of abnormal noise. Also, it is easy to fix the seal piece to the damper board. You can
