Claims

[Scope of Claim for Utility Model Registration] A timer case 7 is provided protruding forward from the gear case 5 of the diesel engine 1, and a mechanical auto timer 10 is provided within the timer case 7. The mechanical auto timer 10 is arranged in order from the back to the front. Main gear 11, advance mechanism 12 and driven flange 1
3, the main drive gear 11 is rotatably fitted and supported on the rear part 16 of the boss cylinder 15 which projects backward from the driven flange 13, and the fuel injection camshaft 17 is fitted and fixed therein. A mechanical auto for a diesel engine is configured such that an oil hole 23 is formed in the middle of the boss cylinder 15 and lubricating oil injected into a boss hole 24 in a boss tube 15 is supplied from the oil hole 23 to an advance mechanism 12 by centrifugal force. In the timer lubricating device, a peripheral wall oil guide protruding surface 29a that guides lubricating oil adhering to the inner surface 26 of the peripheral wall of the timer case 7 to the upper part of the inner surface 27 of the front wall of the timer case 7 is connected to the inner surface 26 of the peripheral wall.
The front wall is formed in a spiral shape twisted in the same direction as the rotational direction of the mechanical auto timer 10 on the upper circumference, and guides the lubricating oil flowing into the upper part of the inner surface of the front wall 27 to the center of the inner surface of the front wall 27. Wall oil guiding protruding surface 30
a is formed in a V shape at the upper part of the front wall inner surface 27, and the lubricating oil guided to the center part of the front wall inner surface 27 by the front wall oil guiding protrusion surface 30a is injected into the boss hole 24. A lubricating device for a mechanical autotimer of a diesel engine, characterized in that the lubrication device is constructed by projecting into the boss hole 24 from the center of the inner surface 27 of the front wall.
