PROBLEM TO BE SOLVED: To provide a locking device of a game machine which is composed of a small number of components and thereby enables the front surface frame (front door) of the game machine to be light in weight and improves the operability of opening and closing the front surface frame (front door). SOLUTION: Hook members 2 and 3 are pivoted so as to be tilted in the direction of the front side at the upper part and lower part on the inner side of the vertical frame 11 of a main body frame 1. The upper and lower hook members 2 and 3 are connected by a connecting rod 4 and an engaging part 4a is provided on a part of the connecting rod 4. A cylinder lock 5 is attached to the vertical frame 11 by inserting a lock shaft to the inner side of the vertical frame and projecting a keyhole surface to the front side of the vertical frame. A cam plate 6 is attached to the distal end of the lock shaft of the cylinder lock 5 so as to be engaged with the engaging part 4a when being turned, and receiving metal fittings 20 and 21 to which the hook members 2 and 3 are to be locked are attached at the corresponding positions on the inner side of the front surface frame. On the front surface frame, an opening recessed part 32 into which the cylinder lock 5 advances when the front surface frame is closed is open. COPYRIGHT: (C)2006,JPO&NCIPI
