PURPOSE: To prevent a bearing material from being out of oil and to improve the wear-resistance by forming an oil hole communicating with a lubricating oil supply path having a designated oil pressure on a support member and supplying lubricating oil from the oil hole to a groove of bush.
CONSTITUTION: A support member 2 includes a shaft 5' rotatably supported thereon through a bush 3. The bush 3 comprises the outer peripheral portion formed by a strength member 3a and the inner peripheral portion 3b. A groove 6 is formed on the strength member 3a extending over the whole outer periphery. A designated number of holes 7 are formed in such a manner as to extend from the groove 6 and pierce through the inner peripheral surface. An oil hole 2a communicating with a lubricating oil supply oil path 9 having a designated oil pressure is formed on the support member 3. The oil hole 2a is adapted to supply lubricating oil in the groove 6 of the bush 3. Thus, the slide bearing material 3b can be prevented from oil deficiency so as to improve the wear- resistance of the bush 3 and seizure-resistance.
