PURPOSE:To prevent vibration from being transmitted to a vehicle body through a body mount by which the vehicle body, a first resilient member, a chassis frame and a second resilient member are coupled, by securing a mount bolt below the second resilient member to a vehicle body through the intermediary of a coupling member. CONSTITUTION:A chassis frame 1 has a chassis bracket 8 secured to a frame body, and a first resilient member 9 is clamped between the bracket 8 and a body bracket 6. A second resilient member 11 is disposed below the first resilient member 9 with the chassis bracket 8 being held therebetween. A mount bolt 13 projecting downward from the second resilient member 11 is firmly secured to a vehicle body 2 through a coupling member 14. Even though the chassis frame 1 vibrates, the vibration is restrained since the mount bolt 13 is retained to the vehicle body 2.
