(Operation) According to the present invention, the bulging portion is pressed against the inner peripheral surface of the outer cylinder as the outer cylinder vertically moves relative to the inner cylinder due to the behavior of the engine when the vehicle starts. After that, since the projecting portion elastically presses against the elastic body and partially absorbs the impact load, the change of the impact load transmitted to the body side becomes gentle, and, for example, when the vehicle suddenly starts. Even when the engine tries to largely move in the lateral direction with respect to the body due to inertial force when the vehicle suddenly stops, the protruding portion elastically presses against the bulging portion and the lateral direction of the outer cylinder relative to the inner cylinder is increased. It restrains the relative movement and prevents the engine from moving in a large lateral direction with respect to the body.

(Effects of the Invention) As described above, according to the present invention, the inner cylinder is disposed inside the outer cylinder, and the elastic body is interposed between the outer cylinder and the inner cylinder. A gap is provided between the inner cylinder and the outer cylinder to allow the inner cylinder to move with respect to the outer cylinder, and the elastic body is provided with a bulging portion that elastically contacts the inner surface of the outer cylinder when a load is applied to the inner cylinder or the outer cylinder. In the tubular engine mount in which the inner spacer is embedded in the bulging portion, the inner cylinder in the vertical direction with respect to the outer cylinder is provided on both sides of the inner cylinder facing the space with the bulging portion in between. During relative movement, the bulging portion elastically contacts the inner surface of the outer cylinder after elastically contacting the elastic body facing the space, and when the inner cylinder laterally moves relative to the outer cylinder, faces the space. By providing a pair of protrusions that can make elastic contact with the bulging portion, for example, the behavior of the engine At the time of relative movement of the outer cylinder in the up-and-down direction with respect to the inner cylinder, after the bulging portion is pressed against the inner peripheral surface of the outer cylinder, the protrusion is elastically pressed against the elastic body. Since a part of the impact load is absorbed, the impact load transmitted to the body side can be moderately changed even if the bulging portion located on the inner spacer cannot have a sufficient thickness. It is possible to eliminate the feeling of starting shock at the time of starting, and even if the engine tends to move largely in the lateral direction with respect to the body due to sudden stop of the vehicle or sudden start, To securely suppress the lateral movement of the outer cylinder with respect to the inner cylinder, in other words, the lateral movement with respect to the body of the engine, while elastically pressingly contacting the bulging portion to absorb the impact load. Can be done. Therefore, as a whole, it is possible to cope not only with large vertical movements of the engine with respect to the body when the vehicle starts, but also with large horizontal movements of the engine with respect to the body due to sudden start, sudden stop, or sudden turn of the vehicle. Was reached.

1. An inner cylinder is disposed in an outer cylinder, an elastic body is interposed between the outer cylinder and the inner cylinder, and the inner cylinder is provided between the elastic body and the outer cylinder. In addition to providing a gap that allows movement with respect to the outer cylinder, the elastic body is provided with a bulging portion that elastically contacts the inner surface of the outer cylinder when a load is applied to the inner cylinder or the outer cylinder,
A cylindrical engine mount in which an inner spacer is embedded in the bulging portion, wherein the inner cylinder has a vertical direction with respect to the outer cylinder on both sides of the inner surface of the outer cylinder facing the gap, with the bulging portion in between. During relative movement to the inner surface of the outer cylinder of the bulging portion after elastically contacting the elastic body facing the gap, and relative movement of the inner cylinder in the lateral direction relative to the outer cylinder,
A cylindrical engine mount, comprising a pair of projecting portions that are in elastic contact with the bulging portion facing the void.
