PROBLEM TO BE SOLVED: To correct variations in the elongation rate of a spring in a shooting device of a pachinko machine by predefining spring locking portions in both a spring-loaded shooting hammer and a tension wheel so that an appropriate elongation rate of the spring is achieved. SOLUTION: Locking portions for the spring 23 are predefined in both the shooting hammer 10 and the tension wheel 37 so that an appropriate elongation rate can be imparted to the spring 23. The first end portion of a wire 22 is locked to a wire cam 17 connected to an operation handle 15 and a plurality of locks 43, 44 and 45 are disposed on the tension wheel 37 locking the second end portion of the wire 22. By varying the tension of the wire 22, the elongation rate of the spring 23 is fine-controlled.
