Abstract
Provided is a stabilizer bush that ensures improved durability. The stabilizer bush (10) comprises: a bush main body (11) formed from a tubular elastic body having a retention hole (12) through which the stabilizer bar (2) passes; a rigid body portion (14) that is fixed to the bush main body (11) and has a higher rigidity than the bush main body (11); and an elastic film (16) that comprises an elastic body and is in contact with a second surface (14b) of the rigid body portion (14). A part of the elastic film (16) is fitted into depressed portions (15a, 15b) that are depressed from the second surface (14b) to a first surface (14a) side.

A stabilizer bush interposed between an installation surface of a vehicle body member and an inner surface of an arch-shaped fixture mounted on the vehicle body member, the stabilizer bush comprising:
- a bush main body formed of a tubular elastic body having a retention hole through which a stabilizer bar passes, the bush main body having a part of an outer peripheral surface in contact with the inner surface of the fixture;
- a rigid body portion secured to a side of the installation surface of the bush main body, the rigid body portion having a rigidity higher than a rigidity of the bush main body;
- and
- an elastic film made of the elastic body interposed between the rigid body portion and the installation surface,
- wherein the rigid body portion includes a first surface with which the bush main body is in contact and a second surface arranged between the first surface and the installation surface, the second surface being in contact with the elastic film,
- a thickness from a surface in contact with the installation surface to a surface in contact with the second surface in the elastic film is thinner than a minimum dimension from the first surface to the second surface, and
- on the rigid body portion, a depressed portion is formed to be depressed from the second surface to a side of the first surface such that a part of the elastic film fits in the depressed portion,
- wherein the rigid body portion on both sides of the depressed portion are integrated.
