に目立つ。2. Description of the Related Art Since rubber has a property of absorbing vibration, it is often used as a support member for supporting a supported member in vibration isolation. However, the coefficient of friction of rubber is not so small,
In addition, since the surface roughness is relatively rough, frictional noise may be generated when the supported member slides on the supporting member, or the sliding resistance may increase, which may be a hindrance. In particular, rubber bushings are often used for the suspension of automobiles,
At places where the road surface has irregularities or the like, the supported member slides in the bush and generates loud friction noise. Such noises are particularly noticeable in modern automobiles, which are all quieter.

ゴムそのものに含有させたものである。As a countermeasure against this, a Teflon sheet having a low coefficient of friction is adhered to the contact surface or a lubricant is applied. The cost is very high, and in the latter case, durability is a problem due to consumption of the lubricant. The present invention solves such a problem, that is, the rubber itself contains fatty acid amide that constantly emerges as a lubricant on the surface of the rubber.

せる性質がある。Fatty acid amide (oleic acid amide) is a substance represented by the existing chemical substance number (2) 976 and having the chemical formula shown in Chemical formula 1. It is a white, neutral powder with a melting point of about 74 ° C. It is insoluble in water, but is quite soluble in organic solvents and highly compatible with resins.
Further, it has a property of dissolving and dispersing various substances (eg, dyes and pigments) well.

である。In the step of kneading the rubber with the fatty acid amide having the above properties, 5 to 30% by weight based on 100 of the raw rubber.
When mixed and molded into a predetermined shape, a rubber part having fatty acid amide protruding on the surface is obtained. The lower limit of the mixing ratio of the fatty acid amide was set to 5% by weight,
If the amount is less than this, the fatty acid amide will be consumed at an early stage. The upper limit is set to 30% by weight. This is because it may have an adverse effect.

When the bearing shaft is supported by the bearing, the fatty acid amide having lubricity as a slimy oozes out on the contact surface of the rubber bush , thereby lowering the friction coefficient between the two, thereby enabling suppression of friction noise and reduction of friction resistance. As soon as the fatty acid amide present on the surface is consumed, the fatty acid amide present inside oozes out, and as long as the fatty acid amide is present inside the rubber, the surface is always kept covered with the fatty acid amide.

Speaking of specific automobile parts, a stabilizer bush, a leaf spring bush, a suspension bush, a spring pad, and the like can be considered.

It can be seen that the required torque is greatly reduced as compared to the case of no inclusion just by being included. It can also be seen that the required torque decreases as the amount of fatty acid amide increases.

If it exceeds hr, the temperature will drop extremely. Therefore, this 30 ph
The vicinity of r can be said to be the limit of the mixing amount.

さない。As described above, since the present invention provides a rubber bush containing a fatty acid amide, the coefficient of friction between the fatty acid amide and a supported portion is reduced by leaching to the surface of the fatty acid amide, thereby suppressing frictional noise. The sliding resistance and the amount of wear can be reduced. And since this rubber bush is obtained without any change in the conventional rubber manufacturing process, the cost is not increased in the process, regardless of the material.
