Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a simple, small-sized fuel injection nozzle selector valve of less flow rate loss for use in selectively changing-over a connected state against two nozzles in a liquid passage arranged inside a main body through rotation of a rotary head installed at the outer periphery of the main body.SOLUTION: A check valve 4 comprises a cylindrical main body 2 including a connection part 2b for an external piping, an annular valve seat 4a and a liquid passage 2a; a sleeve 3 provided with an outlet hole 3a; a check valve 4b opened when pressure in the liquid passage 2a exceeds a predetermined value; and a rotary head 5 including two radial through-ports 5a and two nozzle fixing ports 5b while their peripheral directions being changed, and the rotary head 5 is rotated to cause the two radial through-ports 5a to be selectively connected to the outlet hole 3a.
