Abstract
A tubular antivibration device includes an inner axial member and an outer tubular member that are joined by an elastic rubber main body. The inner axial member is provided with a pair of groove-shaped recesses that open on the outer peripheral surface on both sides in the lateral direction and extend in the vertical direction, and the elastic rubber main body is integrally provided with a pair of upper and lower first elastic joining parts that join the vertically opposing surfaces of the inner axial member and the outer tubular member to each other on both sides in the vertical direction and a pair of left and right second elastic joining parts that join the vertically opposing surfaces of the outer tubular member to each other through the pair of groove-shaped recesses of the inner axial member.
Claims6
A tubular antivibration device in which an inner axial member and an outer tubular member are joined by an elastic rubber main body,
- wherein the inner axial member comprises a pair of groove-shaped recesses that open on an outer peripheral surface on both sides in a lateral direction and extend in a vertical direction,
- the elastic rubber main body integrally comprises a pair of upper and lower first elastic joining parts joining vertically opposing surfaces of the inner axial member and the outer tubular member to each other on both sides in the vertical direction, and a pair of left and right second elastic joining parts joining vertically opposing surfaces of the outer tubular member to each other through the pair of groove-shaped recesses of the inner axial member,
- each of the second elastic joining parts has an axial length that is increased toward both outer sides in the vertical direction, and
- each of the second elastic joining parts has a smallest axial length that is equal to or smaller than a groove width of one of the groove-shaped recesses.
