<p>PURPOSE:To disuse a small diametral oblique hole for lubrication use by installing an iron clutch cylinder which is supported by a static member being pressed-in an aluminum oil pump cover with a cylindrical part via a bearing while also supported by the oil pump cover via a thrust washer. CONSTITUTION:Lubricating oil is fed to a bearing 25 from a first oil hole 27 formed in an oil pump cover 11 by way of a second oil hole 29. Then it is fed to a thrust washer 26 from the first oil hole 27 by way of a third oil hole 30 of a sleeve member 14. At this time the oil pump cover 11 is made of aluminum, through which making it lighter in weight. In addition, any effect due to a difference in a coefficient of thermal expansion with a clutch cylinder 20 is solved by the iron sleeve member 14.</p> |
