Beschreibung
Zusammenfassung:	A diesel engine 1 of the present invention comprises: a camshaft 13 with a cam 21 ; a fuel injection pump 12 having a plunger 84 ; a tappet for driving the plunger 84 ; and a slide portion 2 b. The tappet includes a roller 80 and a roller tappet 82 . The roller 80 serves as a rotor which abuts against the cam 21 so as to drive the fuel injection pump 12 , and a roller tappet 82 serves as a support portion for supporting the rotor. The slide portion 2 b slidably fits to the support portion. The roller tappet 82 has a tappet guide serving as a projection for restriction of rotation, and the slide portion 2 b has a guide groove 92 into which the projection is fitted. Therefore, the rotor and the cam abutting against the rotor can be prevented from abrasion so as to maintain high accuracy in controlling slide stroke of the plunger.
