[Problem to be solved by the invention]

However, in such a conventional automobile pedal mounting structure, the surface rigidity of the dash lower panel 4 is low, and the sound insulation performance of the dash lower panel 4 and the feeling when operating the pedal 1 are poor. No spacer 1
The mounting rigidity of the dash insulator 4 is also low, and the workability and safety during the mounting work of the dash insulator 3 are poor. Further, although the dash insulator 3 is held down by the pedal bracket 2, the rigidity of the dash insulator 3 is low and it bends easily, resulting in poor sealing performance and poor sound insulation performance.

The present invention has been made by focusing on such conventional problems, and improves the sound insulation performance of the dash lower panel and the pedal operation feeling, and improves the workability and safety during installation of the dash insulator. It is an object of the present invention to provide a mounting part structure for an automobile pedal which is improved.

[Means to solve the problem]

In order to achieve such an object, the present invention includes a dash insulator attached to a dash lower panel via a dash lower reinforcement arranged corresponding to a mask bank, and a dash insulator that passes through the dash lower reinforcement and dash insulator. A fixing bolt protruding from the master back and a spacer through which the fixing bolt is inserted are provided in the provided through hole, and by screwing and tightening a nano to the tip of the fixing bolt, the above-mentioned is attached to the lower panel. In an automobile pedal mounting structure in which a master back and a pedal bracket are fixed, the dash lower reinforcement is provided with a jetty that surrounds the outer periphery of the spacer and fits into the through hole of the insulator, while only the outer surface of the dash insulator extends into the through hole of the dash insulator, and this extending portion is held between the top of the jetty and the base surface of the pedal bracket.

[For production]

The rigidity of the dash lower panel is increased by the dash lower reinforcement with a jetty, and the spacer is surrounded by the dash lower reinforcement jetty, increasing the rigidity. Because the jetty is inserted and the extension of the skin of the dash insulator is held between the jetty and the base of the pedal bracket, the rigidity of the dash insulator is increased and the sealing function is achieved. .

In FIGS. 1 to 3, the base end of a pedal 1 is rotatably supported by a pedal bracket 2, and the pedal bracket 2 is fixed to a dash lower panel 4 via a dash insulator 3. A rod 6 extending from a mask bath 5 is connected to the intermediate portion of the pedal 1, and when the pedal 1 is depressed, the rod 6 moves forward and backward, thereby operating the master bath 5.

The dash insulator 3 is made by covering a felt 8 with a skin 9, and an insulator 10 such as Mel sheet is attached to the dash lower panel 4 via a dash lower reinforcement 11 arranged corresponding to the master back 5. is attached to.
