- the dust cover can prevent foreign matters such as sand and pebbles from entering between the stabilizer bar and the one end of the stabilizer bush.

- the increase of the pressure contact force of the dust cover against the stabilizer bar can be suppressed, and the workability of the assembly to the stabilizer bar can be avoided, and stress is concentrated on the dust cover. Can be avoided.
- the side surface on the radially outer side of the annular groove acts as a stopper.
- excessive deformation of the dust cover in the radially outward direction can be restricted.
- the inner peripheral surface portion on the dust cover side is formed in a convex curved surface shape toward the radially outer side.
- the tip surface of the dust cover has a planar shape perpendicular to the axial direction, and the inner peripheral surface portion on the dust cover side is a curved curve that protrudes radially inward at the tip portion of the dust cover.
- a first portion having a planar shape and a second portion connecting the first portion and the distal end surface, and the radius of curvature of the first portion is set larger than the radius of curvature of the second portion Is preferred.
- the annular groove has a radially outer side surface formed in parallel to the axial direction in a cross section along the axial direction, and a radially inner side surface is the axial center. It is preferable that the bottom surface that is formed to be inclined with respect to the direction and that connects the radially outer side surface and the radially inner side surface is formed in an arc shape. Thereby, the stress concentration on the bottom surface of the annular groove can be alleviated and the durability of the dust cover can be improved.
- the annular grooves are provided on both end surfaces in the axial direction, rubber-like elastic body portions radially inward from the annular grooves are formed on the dust cover, and the inner peripheral surface Of these, the inner peripheral surface portion on the one dust cover side and the inner peripheral surface portion on the other dust cover side are more radially inward than the inner peripheral surface portion located between the two inner peripheral surface portions. You can place it on the side. In this way, the dust cover can be provided at both ends in the axial direction of the stabilizer bush.
- the stabilizer bush includes an outer layer rubber and a rubber having a higher slidability than the outer layer rubber in order to prevent generation of abnormal noise due to slip between the inner peripheral surface thereof and the stabilizer bar. It may be composed of a cylindrical rubber-like elastic body having a two-layer structure with an inner layer rubber. In this case, it is preferable that the radially outer side surface of the annular groove is formed by the inner rubber layer. For example, one end portion of the inner layer rubber may bulge radially outward from the other portion of the inner layer rubber, and the annular groove may be provided at one end portion of the bulged inner layer rubber. ,.
- a cutting groove extending from the holding hole for holding the stabilizer bar to the outer peripheral surface is provided, and an outer layer rubber portion facing the cutting groove with the holding hole interposed therebetween is provided. It may be formed in a concave shape on the boundary side with the inner layer rubber.

- the stabilizer bush can be accurately positioned with respect to the suspension member and the bracket. That is, conventionally, this type of stabilizer bush has been formed so that the surface pressed against the bracket is flat across the entire surface. When the bracket and the suspension member are clamped and fixed, the stabilizer bush is covered with the bracket so that the stabilizer bush cannot be observed from the outside of the bracket. For this reason, it was impossible to check whether the stabilizer bushing was correctly attached to the target position with respect to the suspension member. As a result, the stabilizer bush may be attached to the suspension member with a deviation from the target position. For example, the pressed surface pressed against the suspension member corresponds to the uneven pressing surface on the suspension member side.
- the following effects can be obtained by arranging the convex portions as described above. That is, a part of the force acting on the stabilizer bush from the stabilizer bar escapes from the through hole. For example, when the projection is overlapped with the axis of the stabilizer bar when viewed from the clamping direction of the bracket and the suspension member Then, there is a first problem that the force to escape from the through hole is increased, and the spring characteristics of the stabilizer bush cannot be fully exhibited. In addition, this structure has a second problem that the force acting on the base of the convex portion from the stabilizer bar and the bracket becomes large, and the base portion is likely to crack.

Therefore, the force to escape from the through hole is small, and the first problem can be avoided. And since the force acting on the base of the convex portion from the stabilizer bar and the bracket becomes small, the second problem can be avoided.

- the shaft core 02 of the stabilizer bar 1 Seen from the clamping direction Z, the shaft core 02 of the stabilizer bar 1, the shaft core 03 of the convex portion 38, and the force are separated in a direction T perpendicular to the shaft core 02 of the stabilizer bar 1.
- the convex portion 38 is arranged so that the entire convex portion 38 protrudes from the outer peripheral surface 1 A of the stabilizer bar 1 to the radially outer side K2 of the stabilizer bar 1.
- the present invention can be used as a stabilizer bush used to support a stabilizer bar hung between left and right suspensions of an automobile.
- FIG.2 View of stabilizer bush viewed from one outer side in the axial direction
