PROBLEM TO BE SOLVED: To provide a fuel injection device for a hydrogen rotary engine capable of inhibiting abnormal combustion and improving mileage. SOLUTION: The fuel injection device for the hydrogen rotary engine 1 includes a hydrogen injectors 40, 42 directly injecting hydrogen into a working chamber 10 of the hydrogen rotary engine, a hydrogen injection timing control means controlling injection timing for the hydrogen injectors to inject hydrogen into the working chamber at a predetermined timing during compression stroke, and a hydrogen flow out direction setting means setting hydrogen injection direction to make hydrogen from the hydrogen injector flow out toward a leading area L of the working chamber in a low rotation speed area of the hydrogen rotary engine and flow out toward a center area of the working chamber in a high rotation speed area.
