As shown in the accompanying drawings, in the structure for fixing the pivot 22 of the windshield wiper device 20 for wiping the windshield 11 of the vehicle on the upper portion of the dash panel 10, the dash panel ( One end is fixed to the bottom of one side of the 10), the middle portion is bent and the other end of the first bracket 30 is formed with a first coupling hole 32 is opened on the right side, and the other end of the dash panel 10 once The second bracket 30 having the second fixing hole 42 having the welded, the intermediate part bent and the other end opening on the other end surface thereof is coupled to the first coupling hole 32 of the first bracket 30. The first pivot member 50 having the first threaded portion 52 formed at the upper end thereof, and the second pivot having the second threaded portion 62 formed at the upper end thereof so as to be coupled to the second coupling hole 42 of the second bracket 40. A second threaded portion inserted into the member 60 and the first coupling hole 32 of the first bracket 30 and the second coupling hole 42 of the second bracket 40 ( 62) and a fixing nut 70 fastened to the first threaded portion 52, and reference numeral 80 is a connecting rod.

Referring to the operation of the present invention configured as described in detail as follows.

The first panel 30 having the first coupling hole 32 having the right opening at the upper surface thereof and the second bracket 30 having the second coupling hole 42 having the opening opening at the upper surface thereof are formed at the dash panel. In the state where the other end is welded and fixed to the bottom of one side of the 10), the first threaded portion 52 formed on the upper end of the first pivot member 50 is formed by opening the right side on the upper surface of the first bracket 30 The first coupling hole is formed by inserting the right side of the first coupling hole 32 and opening the second threaded portion 62 formed at the upper end of the second pivot member 60 on the upper surface of the second bracket 40. When fitted in front of the 42, the first pivot member 50 and the second pivot member 60 connected to each other by the connecting rod 80 is the temporary coupling is completed.

When the fixing nut 70 is fastened to the first threaded portion 52 and the second threaded portion 62 of the first pivot member 50 and the second pivot member 60 in which the temporary coupling is completed, the connection rod ( The first pivot member 50 and the second pivot member 60 interconnected by 80 are stably fixed to and coupled to the dash panel 10.
