PURPOSE:To eliminate necessity for use of any liner and thereby reduce the weight of a locker arm made of a light alloy and equipped with zero-lash adjuster, by furnishing an alumite layer impregnated with solid lubricant at the sliding part of locker arm with the zero-lash adjuster. CONSTITUTION:A locker arm 1001 is made of light alloy, and an alumite treated layer impregnated with solid lubricant is formed at the internal surface 1000a of cylinder 1000, with which the plunger of zero-lash adjuster slides. This treated layer serves enhancement of the lubricating performance, that will ensure smooth operation without resorting to a linear made of iron, copper, etc. Besides this, the weight of locker arm can be reduced. |
