The present disclosure provides a mount for a vehicle that is provided at a portion at which damping performance is desired and that is fastened by a stud bolt. The mount for the vehicle includes a flange into which the stud bolt is inserted and that supports the stud bolt, an insulator configured to surround the flange, a housing coupled to the other one of the vibrating body or the supporting body and to which the insulator is fixed, a chamber formed inside the housing as a space surrounded by the housing and the insulator, and the chamber is filled with a fluid. In addition, the mount for the vehicle includes a damping part mounted on the housing to divide the chamber into two spaces and to be disposed in the chamber. The mount for the vehicle is configured to appropriately absorb vibrations and reduce noise.

A pair of bracket fastening parts (7, 12, 91, 92, 121, 122, 161, 162) are provided on a side of the main body in an adjoining relationship, each bracket fastening part including a plurality of bosses (32 to 35, 72 to 75, 102 to 106, 132 to 137) arranged in a convex polygonal pattern and a plurality of ribs (37 to 42, 60, 80 to 84, 110 to 115, 140 to 146) connecting the bosses in a prescribed pattern. At least two of the bosses of one of the bracket fastening parts are shared by an adjoining one of the bracket fastening parts. Thereby, the engine can be adapted for multiple applications while minimizing an increase in the weight of the engine.

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 vibration damping device for a vehicle includes: a first attachment member attached to a first member; a second attachment member attached to a second member; a first liquid chamber and a second liquid chamber configured to change volumes according to relative displacement between the first attachment member and the second attachment member; and an orifice passage configured to cause a liquid to flow between the first liquid chamber and the second liquid chamber according to changes in the volumes of the first liquid chamber and the second liquid chamber. The orifice passage is curved at least partially in an axial direction thereof, and the liquid contains a non-Newtonian fluid whose viscosity decreases as a shear rate increases.

A present invention provides an anti-vibration device (1) which is equipped with a first tubular mounting member (11) connected to one of a vibration generating part and a vibration receiving part, and a second mounting member (12) connected to the other thereof; an elastic body (13) which connects the first mounting member and the second mounting member; and a partition member (16) which partitions a liquid compartment (19) in the first mounting member into a first liquid compartment (14) having the elastic body in a part of a bulkhead, and a second liquid compartment (15) in an axial direction along an central axis of the first mounting member, and has an orifice passage (24) through which the first liquid compartment and the second liquid compartment communicate with each other, in which a plurality of ridge parts (26) extending in a circumferential direction are formed on an inner surface (27) of the elastic body which defines the first liquid compartment in a radial direction.

This vibration-damping device is configured such that an outer mounting member (11), an inner mounting member (12), or a partition member (16) has formed therein: a first restriction passage (23) for providing communication between a fourth liquid chamber (21) and a second liquid chamber (15) or a third liquid chamber (20); and a second restriction passage (24) for providing communication between the second liquid chamber (15) and the third liquid chamber (20). The flow resistance of the first restriction passage (23) and that of the second restriction passage (24) are different.

A vehicle includes a case member, a stay member and a rib. The case member is supported by a frame of a vehicle body with a mount member being interposed. The stay member is suspended between a boss part of the case member and a member of a case member side in the mount member, a longitudinal direction of the stay member intersecting a longitudinal direction of the frame. The rib extends in the case member in a direction that is an extension of the longitudinal direction of the stay member at a root of the boss part.
