Abstract:
1. An anti-vibration connecting rod, comprising: a rod body including first and second cylindrical parts disposed to be spaced apart from each other in a main-load application direction; a first inner cylinder located in the first cylindrical part, and coupled to an inner surface of the first cylindrical part through a first elastic member, a connected member being attached to the first inner cylinder; a second inner cylinder located in the second cylindrical part, and coupled to an inner surface of the second cylindrical part through a second elastic member, another connected member being attached to the second inner cylinder; and a stopper located in the first cylindrical part, and configured to restrict an amount of relative displacement of the first inner cylinder relative to the rod body in the main-load application direction, wherein the first elastic member is integrated with the inner surface of the first cylindrical part and an outer surface of the first inner cylinder, the stopper includes a stopper body which is a part of the inner surface of the first cylindrical part facing the first inner cylinder in the main-load application direction and projecting inward in a radial direction of the first cylindrical part, the stopper body has a substantially trapezoid shape whose width gradually increases outward in the radial direction of the first cylindrical part and whose distal surface is a flat plane perpendicular to the main-load application direction, the stopper further includes a stopper elastic part made of an elastic body provided in the distal surface of the stopper body, a recess which is open to a first inner cylinder side is provided in a part of the distal surface of the stopper body located on a line passing through a cylinder axis of the first inner cylinder and extending in the main-load application direction when viewed along the cylinder axis of the first inner cylinder, and the stopper elastic part covers the entire distal surface of the stopper body to fill the recess, and has a distal surface which is a flat plane perpendicular to the main-load application direction.
