A structure of a rear suspension arm mounting unit is provided to increase durability by inserting an upper arm reinforcement plate for surface-contacting an upper arm bush with a pipe nut and thereby distributing load through the upper arm. A structure(1) of a rear suspension arm mounting unit for mounting an upper arm(300) and a lower arm(100) on a rear side frame(200), comprises as follows. A lower arm mounting unit includes a bush surrounding the lower arm, a lower arm bracket(11) fixing the lower arm, a reinforce bracket supporting a lower end of the side frame and a lower arm bracket reinforcement plate(13) fitted between both surfaces of the lower arm bracket. An upper arm mounting unit includes the bush, a front upper arm bracket, a rear upper arm bracket and an upper arm reinforcement plate. A pipe nut is installed by penetrating the lower arm bracket. In addition, an auxiliary reinforcement plate(50) is installed to the outside of the lower arm bracket. |
