Abstract: There is provided an oil feed member capable of preventing lubricant from being excessively fed from an oil feed member to lubrication portions of valve gears, and a lubricant feed mechanism for an engine provided with the same. An oil feed member for feeding lubricant to lubrication portions of valve gears for opening and closing intake valves and exhaust valves of an engine, the oil feed member including: an upper panel member and a lower panel member laid over each other; and an oil feed passage formed by recessing laid surfaces of the upper panel member and the lower panel member, wherein the oil feed passage includes basis oil passages formed on a downstream side, and an introduction oil passage formed on an upstream side and having a smaller lubricant flow area than that of the basis oil passages.

Abstract: A manufacturing method of an end plate of a pump that can remove a sag includes: punching a workpiece from a plate material, the workpiece being the end plate including a mounting seat including a fastener; forming a pressed trace surface by pressing an outer edge of an outer surface, when a surface, of both front and back surfaces of the punched workpiece, further from a sag formed on a cut end surface is the outer surface, and a surface, of both front and back surfaces of the punched workpiece, nearer to the sag is an inner surface. A section of the pressed trace surface disposed along an outer edge of the mounting seat is a fastening section. A section of the pressed trace surface other than the fastening section is a non-fastening section. A radial width of the fastening section is shorter than that of the non-fastening section.

Abstract: Provided are an oil feed member that makes it possible to ensure a wide distance between oil passages and to achieve space saving in the oil passages and a lubricant feed mechanism of an engine provided with the oil feed member. An oil feed member includes a lubricant passage and a plurality of discharge ports that are formed on the downstream end of the lubricant passage and discharge lubricant flowing through the lubricant passage to a lubrication portion. The lubricant passage includes a basis oil passage, a first upstream branch oil passage that branches off from the basis oil passage and allows lubricant guided to the discharge ports to flow therethrough, and a second upstream branch oil passage that branches off from the basis oil passage and allows lubricant guided to the discharge ports to flow therethrough.
