PURPOSE:To miniaturize the device by reducing a clearance between the fuel valve and the adaptor table of a valve arm remarkably and reduce the number of parts for attaching the device by a method wherein a valve pressing member and a valve arm bonnet are fixed to a cylinder head through a tightening nut screwed onto the extended screw part of a tightening bolt for fixing the adaptor table of the valve arm. CONSTITUTION:The tightening bolt 33 at the side near a fuel injection valve 30, among the tightening bolts 33, 34 for fixing the valve arm adaptor table 32 to the cylinder head 24, is provided with the extended screw part 33', screwed with a male screw on the outer periphery thereof from a part, whereat the nut 35 is screwed, or the upper surface 32a of the valve arm adaptor table 32 to the upper part thereof, and holds a valve pushing member 36, whose one end is formed so as to have a branched pushing part 36a abutted against the shoulder 30a of a fuel valve 30 while the other end is formed as a support point 36b bent into a hook-shape, further, the valve arm bonnet 39 is capped so as to cover all of these parts. |
