When an insulator is of non-circular shape, a spring ratio of an X direction to a Y direction is increased by utilizing this non-circular shape. A pair of direction elastic walls opposed to each other in the X direction is formed short and thin in the Y direction and has a small X direction projected area. Similarly, a second mounting metal fitting is formed in a rectangular shape extending long in the X direction and includes a pair of X direction restraint walls opposed to each other in the X direction and a pair of Y direction restraint walls opposed to each other in the Y direction. A first mounting metal fitting includes a pair of X direction restraint projecting parts opposed to each other in the X direction and a pair of Y direction restraint walls opposed to each other in the Y direction.

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.

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.

A connecting structure which reduces a vibration effect of a power system on a vehicle body comprises a power system bracket, one end of the power system bracket being connected to a power system, another end being connected to a suspension, one end of the suspension being connected to a frame or a load-bearing vehicle body, another end being connected to an axle or wheels, the suspension being capable of attenuating and isolating high frequency vibrations produced by the power system. The power system is not directly connected to the vehicle body which is above shock absorbers, but rather connected to a suspension frame which is below the shock absorbers, extending the path whereby power system high frequency vibration energy is transferred to the vehicle body, so that the high frequency vibrations of the power system are effectively attenuated and isolated, and the vibrations of the vehicle body are reduced.

To provide an engine unit support structure with excellent vibration damping performance and durability, the engine unit support structure (1) is provided with an engine unit (2) having an engine (22), a mounting base (3) for mounting the engine unit (2) thereon, and a plurality of elastic support bodies coupled to the engine unit (2) and the mounting base (3) to thereby support the engine unit (2), in which the plurality of elastic support bodies include a first elastic support body (4A) disposed under the lower surface (20) of the engine unit (2) in a position closest, than any other of the plurality of the elastic support bodies, to the rotation center of the output shaft of the engine (22) and three or more of second elastic support bodies (4B, 4B, . . . ), and the first elastic support body (4A) is disposed within a closed space X in plan view formed by interconnecting the centers of the neighboring second elastic support bodies (4B, 4B, . . . ).

Disclosed is a dog-bone type rear roll rod in which a body bracket, which is fixed to a vehicle body, and front and rear rubbers, which are disposed at front and rear sides of the body bracket, respectively, are connected together through an inner pipe and fastened to a rod by means of a fastening member, the dog-bone type rear roll rod including: an extrusion plate which has a through hole formed such that the inner pipe penetrates a center of the extrusion plate, has a width length greater than a width length of the rod, and is press-fitted between the rod and the front rubber.

In a mounting structure for a fuel cell drive system, a mount member includes a first mount and a second mount. The first mount connects the first end of a stack case to the first frame. The second mount connects the second end of an auxiliary device case to the second frame. The fuel cell drive system includes a first connecting member and a second connecting member. The first connecting member connects the stack case and a motor to each other. The second connecting member connects the auxiliary device case and a speed reducer to each other.

A first mounting metal fitting is connected to an engine while a second mounting metal fitting is mounted on a vehicle body. A vibration isolating elastic body provides a connection between the first and second mounting metal fittings. Middle portions of opposed upwardly extending wall sections are formed in a concave curve surface, and expanded recess portions are provided between the opposed upwardly extending wall sections. A projecting section provided on the first mounting metal fitting is accommodated in the expanded recess portions. The projecting section overlaps with the expanded recess portions in the X direction so as to regulate the movement in the X direction of the first mounting metal fitting. The X direction elastic leg for regulating the movement in the X direction is not provided, so that the molding can be performed by demolding a molded object in the X direction.
