PURPOSE:To make the projection of a guide pin variable while to prevent falling of guide pin in a fuel injection pump, by securing the stopping section in a guide pin pass hole of housing while providing shallow and deep stopping grooves at the tip of the guide pin. CONSTITUTION:A guide pin 19 is provided while penetrating through housing 1 on the outer face of housing 1, and inserted in a guide groove 20 formed in a tappet body 6 of a tappet 5 at the tip. Consequently each tappet 5 is prevented from rotation and falling. The guide pin 19 is formed with shallow and deep cross-shaped stopping grooves 21, 22 in the head section 19a where the stopping section 24 is pressure inserted in a holding hole 25 made from the bottom of housing 1 toward a through-hole 23 then engaged with shallow stopping groove 22 of the guide pin 19 thus to prevent removal of guide pin 19. |
