のである。2. Description of the Related Art A stabilizer bar is provided in order to suppress rolling of a vehicle body by connecting movements of independent left and right wheels to improve riding comfort or running stability. For example, as shown in FIG. 3, when the one provided at the front of the automobile is taken as an example, the central portion 52a of the stabilizer bar 52 bent in a substantially U-shape is installed at a right angle to the center line of the vehicle body. Mounting brackets 151, 15 are rotatably mounted on a vehicle body (not shown) through the bushes 130, 130.
The ends of the bent and supported end portions 52b, 52b are connected to suspension arms 56, 56 installed on the lateral sides of the vehicle body. With this configuration, when the suspension arms 56, 56 move due to unevenness of the road surface, braking of the vehicle, turning of the vehicle, or the like,
Both ends 52b, 5 of the connected stabilizer bar 52
As for 2b, the central portion 52a attached to the vehicle body is the bush 13
It swings about 0 and 130 as fulcrums. Therefore, when the left and right wheels 55, 55 change the phase in the same direction by the same amount, the swing angles of the both end portions 52b, 52b are the same on the left and right, and the stabilizer bar 52 is the bushes 130, 130.
It simply rotates around the
When the phases of 5 and 55 are upside down, or the movement amounts are different even in the same direction, the swing angles of both end portions 52b and 52b with respect to the vehicle body are different from each other, and the central portion 52 of the stabilizer bar 52 is different.
An elastic twist is generated in a. That is, the twisting reaction acts to equalize the left and right suspension positions connected by the stabilizer bar 52, and contributes to the stability of the vehicle body.

In the support of No. 2, the support center of the central portion 52a of the stabilizer bar 52 may be lowered downward (toward the ground) from the vehicle body 50 in order to reduce the sinking of the front end of the vehicle that occurs during braking. This separation distance may be different. In this case, it is sufficient to lower the mounting positions of the bushes 130, 130 on the vehicle body side, but changing the vehicle body increases the cost significantly, and there are also factors that cannot uniquely determine the movement amount. Part 52
The modification is made on the side of the bush 130 that extends the distance from the mounting surface of the bushes 130, 130 supporting a to the through hole.

いる。The bush is formed of an elastic member as described above. For this reason, if the separation distance to the through hole is extended, the supporting rigidity of the bush is reduced, and the original function of the stabilizer bar is reduced.
For example, Japanese Utility Model Publication No. 60-8118 proposes a bush reprinted as FIG. 4 of the present application. Specifically, the hard material 220 is embedded between the through hole 211 in which the stabilizer bar 52 is mounted and the mounting surface 223 that abuts on the vehicle body 50, and the width is the same as that of the main body 210 or slightly shorter than this. The hard material 220 is integrally formed.
Even when the separation distance L is increased, the bush 230 is reinforced, so that the original function of the stabilizer bar 52 is not deteriorated, and the sinking of the front end of the vehicle that occurs when the vehicle is braked during traveling is reduced. Is playing.

Since the main body is made of an elastic material, proper vibration-proof support can be performed, and the stabilizer bar can be easily attached to the through hole of the main body by expanding the slit provided on the outer edge. Even if the distance between the through hole of the bush and the mounting surface is increased, a hard material with a thickness approximately equivalent to the increase is connected to the other end surface of the main body as a pedestal, so the supporting rigidity required for the bush is maintained and the distance is increased. It does not cause the stabilizer bar to deteriorate due to the increased distance. Further, since the main body and the pedestal are connected to each other without being separated, they can be handled as one component and the component management is easy. And, unlike the conventional technique, in which the hard substance floats between the through hole and the mounting surface, the pedestal made of the hard substance is connected to the end face of the main body and is exposed to the outside, so when manufacturing the bush. The pedestal is in direct contact with the cavity surface in the mold. Therefore, the structure for positioning and holding the pedestal can be very easily utilized by utilizing the cavity surface. Further, the rigidity can be changed as needed by changing the thickness of the pedestal, so that the mold can be easily changed. Since the connecting portion is formed by filling the connecting hole of the pedestal with the elastic material extending from the main body, the pedestal is connected to the main body without adhesion. Therefore, no bonding process is required to connect the pedestal and the main body, and the product cost can be reduced. Moreover, since the groove is provided along the ridge of the outer edge, it is possible to use this to devise the mold side to more accurately position and hold the pedestal in the mold.

Further, in the configuration in which the cavity is arranged so that the through hole 11 faces upward in the horizontal direction indicated by the arrow P in FIG. 1, the pedestal 20 needs to be arranged in the mold with its end face standing vertically. In this state, if one end face 23 is brought into contact with the cavity face and the other end face 24 is supported by the protrusion of the cavity portion forming the groove 16, the fall can be prevented,
Positioning and holding can be done easily. However, even without such a method, the pressure applied to the other end surface 24 side of the pedestal 20 by the injection pressure of the elastic material at the time of molding the main body is essentially larger than the pressure applied to the one end surface 23 side. Therefore, the pedestal 20 is naturally pressed against the cavity surface. That is,
Since the pedestal 20 is exposed to the outside of the main body 10, the pedestal 20 is pressed against the cavity surface by the injection pressure in the mold, and directly comes into contact with the cavity surface. Various support methods are possible using direct contact.

ようになった。As described above, according to the present invention, the pedestal is exposed to the outside of the main body, rather than the structure in which the hard material is floated between the through hole and the mounting surface as described in the prior art.
At the time of manufacturing the bush, the end surface of the pedestal at the outermost end can be directly brought into contact with the cavity surface and supported, so that not only positioning and holding of the pedestal can be performed very easily, but also the mold structure can be facilitated. Further, in the present invention, the dimensional change of the hard material due to the change of the rigidity, which is carried out as necessary, can be dealt with by the change of the thickness of the pedestal, so that the change of the mold is facilitated. Further, since the pedestal and the main body are not bonded to each other by the connecting portion, there is no need to perform a process for bonding the pedestal to the main body, and positioning and holding of a hard substance are easy, so that manufacturing workability is improved. As described above, the structure of the bush for the stabilizer bar, which has the effect of reducing the cost as compared with the bush of the conventional technology, can be provided.
