。[Scope of Claim for Utility Model Registration] (1) In a substantially cylindrical valve guide that is fitted into the valve box of a diesel engine and into which the valve stem is inserted, a supply groove for circulating lubricating oil is provided on the outer peripheral surface of the valve guide. A through-hole is provided to allow lubricating oil to flow from the supply groove to the inner surface of the valve guide, and the lubricating oil forced into the supply groove is forcibly supplied to the vicinity of the lower end between the valve guide and the valve stem. A valve guide for a diesel engine that is characterized by: (2) The valve guide for a diesel engine according to claim 1, wherein the supply groove is spirally formed from the top to the bottom of the valve guide. (3) The valve guide for a diesel engine according to claim 1, wherein a recirculation groove is formed on the inner surface of the valve guide to recirculate the pumped lubricating oil from the lower part to the upper part of the valve guide.
