PROBLEM TO BE SOLVED: To provide a prize-winning device for a Pachinko machine wherein the working force of a solenoid is surely transmitted and a front door is opened and closed only by energizing the solenoid momentarily. SOLUTION: The prize-winning device is provided with: a casing 2 which receives balls from a prize-winning port 1; the front door 3 pivotally supported by a side wall 28 of the casing 2 and opening and closing the port 1; and a plunger-type solenoid 4 rotating the front door 3. A cylindrical object 6 having a cam curved line 5 formed on its outer peripheral surface is mounted to the tip of a plunger 41, and a contactor 7 to be engaged with the cam curved line 5 is made projecting at the casing 2. By attracting the plunger 41 and making it project to move the cylindrical body 6 forward and backward while rotating according to the cam curved line 5, the cylindrical body 6 pressurizes an engaging projecting piece 32 at the lower part of the front door 3 to rotate the front door 3.
