Abstract: This invention provides, in a vibration isolating bushing comprising an inner and an outer cylinders cencentrically spaced apart and a rubber elastomer interconnecting both cylinders by vulcanization forming, such that it is possible to ensure sufficiently a forcing allowance of the outer cylinder when press fitted to a support member, to improve the workability upon assembling, and to avoid the outer cylinder from releasing and dropping off from the inner cylinder even if the rubber elastomer is ruptured. According to its expedient, the inner cylinder is formed at its axial extremities with outwardly upset portions, the outer cylinder is formed at its one axial extremity with a flange portion having a larger diameter than an outside diameter of the upset portion, and an inside diameter of the extremity of the outer cylinder is made smaller than the outside diameter of the upset portion.

Abstract: A vibration-isolating bushing, with which downsizing and weight reduction are attainable and the face pressure of the edge face of an inner cylinder can be reduced, comprises an inner cylinder having a bulge portion bulging in an axially central area thereof in an axially square direction, an outer cylinder disposed outwardly of the inner cylinder in a spaced relationship, and a rubber-like elastomer interposed between the inner and outer cylinders and vulcanization-molded. After the vulcanization molding, an upset portion is formed at one extremity of the inner cylinder in a larger wall-thickness than that of other part by abuttingly forcing an axially one edge face of the inner cylinder on a contact-pressing jig in the axial direction, whereby the area of the edge face is enlarged.

Abstract: A structure for a bushing disposed between inner and outer cylindrical members arranged concentrically to each other, comprises an elastical member fitted into the inner periphery of the outer cylindrical member, a substantially cylindrical slidable member disposed between the inner cylindrical member and the elastical member, and a projecting lip portion formed on at least one of the outer circumferential surface of the inner cylindrical member and the inner circumferential surface of the slidable member, such that the projecting portion keeps in contact with the opposing circumferential surface with a small contact area and defines a slight aperture between the outer periphery of the inner cylindrical member and the inner periphery of the slidable member.

Abstract: A dust seal for a sliding type bush is interposed between a stationary section and a movable section. The dust seal has a fitting portion fitted to the stationary section, a seal lip portion in sliding contact with the outer circumferential surface of the movable section and a flexible portion interconnecting the fitting portion and the seal lip portion. The dust seal is further provided with an annular projection held in contact with a flange and the outer circumferential surface of the movable section. The seal lip portion is held axially stationarily relative to the movable section.
