Stopper structure for engine mount

A stopper structure for an engine mount including an elastic body elastically connecting two mounting members, the stopper structure comprising:

• a rigid abutting member connected to one of the two mounting members, and extending in a longitudinal direction with a substantially rectangular shape in cross section;
• and
• a rubber stopper including:
• a base portion of tubular shape in cross section, and being secured press-fit onto the rigid abutting member without being adhesive to a superficial surface of the rigid abutting member;
• a pair of peripheral projections formed on laterally opposite sides of a first abutting plane of the base portion and extending in the longitudinal direction of the rigid abutting member;
• and at least one central projection formed on an intermediate area interposed between the pair of peripheral projections of the first abutting plane surface of the base portion,
• wherein the pair of peripheral projections are situated on laterally opposite edges of a corresponding first abutting plane of the rigid abutting member, respectively, and have a width dimension extending inside and outside the edges of the rigid abutting member, wherein the at least one central projection projects outward from the first abutting plane of the base portion with a height dimension the same as that of the pair of peripheral projections,
• wherein the first abutting plane of the base portion is brought into abutting contact with an abutting portion provided by a member connected to an other one of the two mounting member, upon application of a vibrational load to the engine mount in a bound direction, and
• wherein each of the pair of peripheral projections provides a substantially flat abutting surface on a projecting portion thereof, and the at least one central projection has a cone-like shape.
