FUEL INJECTION DEVICE

WIPO Patent Application WO/2017/022163

A1

A gap-forming member (60) has a plate section (61) provided to the side of a needle (30) that is opposite of a valve seat so that one end surface can come into contact with the needle (30), and an extended section (62) extending toward the valve seat from the plate section (61) and formed so that the end on the side opposite the plate section (61) can come into contact with a surface of a movable core (40) on a side facing a fixed core (50). When the plate section (61) is in contact with the needle (30) and the extended section (62) is in contact with the movable core (40), the gap-forming member (60) can form an axial gap (CL1), which is a gap in the axial direction between a ridge part (33) and the movable core (40). A first wall surface (601) of the gap-forming member (60), which is a wall surface facing an outer wall of the ridge part (33), is capable of sliding against the outer wall of the ridge part (33), and a second wall surface (602) of the gap-forming member (60), which is a wall surface that faces an inner wall of the fixed core (50), together with the inner wall of the fixed core (50) forms a diametral gap (CL2) which is a gap in the diametral direction.
