PROBLEM TO BE SOLVED: To reduce costs by simplifying the structure of a lock device. SOLUTION: The lock device of a Pachinko machine which is mounted on a surface frame 3 has a mobile locking plate 40 which slides in the unlocking direction receiving the force in the direction of unlocking the body of the lock device, an engaging pawl 20 which is rotatably mounted on the surface frame 3 and receives the actions of the mobile locking plate 40 sliding in the unlocking direction to turn in the unlocking direction from the locked position and an engaged piece 30 which is mounted on a glass frame 5 and lets the engaging pawl 20 in the locked position be engaged therewith. The engaging pawl 20 is provided with a pressing part 24 adapted to press the glass frame 5 to be opened when this pawl 20 turns in the unlocking direction from the locked position.
