Abstract

A coupler buffer device mounting structure for small-fastening-torque pushing under a compact space includes a double-headed stud passing through an installation fabrication hole of a vehicle body structure; a nut screwed on a first end of the double-headed stud; a push nut screwed on a second end of the double-headed stud and provided with a plurality of axial screw holes in a circumferential direction; and a plurality of push screws screwed into the circumferentially provided axial screw holes of the push nut, where the coupler buffer device is clamped and fixed to the vehicle body structure by heads abutting against the coupler buffer device via a hard washer. The coupler buffer device mounting structure achieves the passing of the double-headed stud from a coupler side to a vehicle body side by using the double-headed stud, the nut, the push nut and the plurality of push screws in combination.
