An object of the present invention is to provide a mounting member structure capable of preventing unstable vibration of an engine mount. A mounting member structure, which is mounted on a power plant including an engine and has a mounting member disposed between the power plant and an antivibration device, wherein the mounting member has an opening abutting the power plant and an inner space continuous from the opening, a weight mass is disposed in the inner space, and the weight mass is fixed to a recess in the inner space through a first bolt. The mounting member is fastened to the antivibration device by a second bolt.

Mounting member structure

A mounting structure for mounting a dynamic damper on a vehicle body frame of a vehicle includes a dynamic damper mounted on a vehicle body frame of a vehicle includes a dynamic damper bracket connecting the dynamic damper to the vehicle frame; a collar member rigidly fixed to the vehicle body frame; a mounting bracket which is mounted above the vehicle body frame, and which is elastically connected to the collar member; and a fixing member which fixes the dynamic damper bracket and the collar member to the vehicle body frame.

Dynamic damper mounting structure

A stay includes a first-bolt hole portion fastened to a body frame by a first bolt, a second-bolt hole portion fastened to a subframe by a second bolt, a recessed portion disposed between the first-bolt hole portion and the second-bolt hole portion and recessed downward, and a cutout portion continuous with the first-bolt hole portion and formed by cutting out a part of the recessed portion. The dimension of the recessed portion in its depth direction is equal to or larger than the dimension of the head portion of the first bolt in its height direction. The widthwise dimension of the cutout portion in a direction perpendicular to an axis of the stay is set to be smaller than the largest outer diameter of the head portion of the first bolt.

Stay drop-off structure in case of impact load input

An engine mount structure capable of efficiently absorbing vibration input from an engine is provided. The engine mount structure includes a front mount devicewhich is connected to an engineand a subframeto suppress vibration transmission from the engineside to the subframeside. A dynamic damperconnected to the subframeto suppress vibration of the subframeis disposed in a hole portion, and an opening of the hole portionis formed in an upper surface portionof a front subframe member componentlocated on a lower side of the front mount device

Engine mount structure

A pair of side members extends in a longitudinal direction of a vehicle in a width direction and have a plurality of coupling portions coupling with a vehicle body member of a vehicle. A pair of cross members extends in the width direction to face each other in the longitudinal direction and couple the pair of side members. A pair of coupling members is provided in the side members to couple a corresponding one of the plurality of coupling portions with the vehicle body member. A pair of support members is provided in the cross members to support correspondingly a pair of suspension arms provided in the vehicle and facing each other in the width direction. The lower parts of the support members are welded to upper walls of the coupling members and vertical walls of one of the cross members straddling the upper walls and the vertical walls.

Sub-frame for vehicle

In a vehicle front body structure, a subframe is provided below a left front side frame and a right front side frame. The left front side frame has a first fragile portion. The subframe has a second fragile portion and an extension portion. When a bumper beam's left end portion and a left bumper beam extension are crushed by an impact load, a front surface of the bumper beam's left end portion comes to substantially the same position as a front edge portion of the extension portion.
