Support structure of fuel injector

Abstract

A cylindrical fuel injector (1) has a projecting part (2) projecting in a lateral direction. A cylinder head (5) has a hole (18) for inserting the fuel injector (1). An elastic member (6) is formed in a cylindrical shape with a notch to have a C-shaped cross-section. The elastic member (6) is fitted to the fuel injector (1) on the opposite side from the projecting part (2) to elastically support the fuel injector (1) in a state where a tip (1a) of the fuel injector (1) is inserted into the hole (18). A support member (3) supports the elastic member (6) and a snap ring (16) prevents deformation of the elastic member (6) in a lateral direction with respect to an axis of the fuel injector (1) under a compressive load exerted by the engine member (5) and the support member (3).
