Abstract

An oil strainer for a transmission including a resin-made upper case which is formed in a side surface of an upper part of a communication port for communication with a pump and which has an upper flange along the outer periphery thereof, a resin-made lower case which is provided with an oil suction port in a lower surface thereof and which has a lower flange joined to the upper flange of the upper case, and a filter member which is disposed in a space formed by joining the upper and lower cases and which filters an oil flowing from the oil suction port to the communication port. The oil strainer is configured to further includes an oil suction port cover member which is so formed as to cover at least an inside upper surface of the oil suction port and which forms a passage for conducting the oil to the filter member.

Description

[0001] This is a continuation of International PCT Application NO. PCT / JP2007 / 057235, filed Mar. 30, 2007, which was not published in English.BACKGROUND OF THE INVENTION

[0002] 1. Field of the Invention

[0003] The present invention relates to an oil strainer for filtering an oil in a transmission case.

[0004] 2. Description of the Related Art

[0005] An oil used as a working fluid or a lubricating oil in a transmission is reserved in a lower part of a transmission casing, is sucked by an oil pump and is supplied to a control valve and other parts to be lubricated. In this case, it is a common practice to disposed an oil strainer in the lower part of the transmission casing and to filter the oil through the strainer before the oil is sucked by the pump. A configuration in which a filter member formed from a non-woven fabric or the like is disposed in a resin-made case to form the oil strainer has been known. In this case, the filter member composed of the non-woven fabric is clamped between an...
