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 ( 1 a) 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 ).
