  When the above locking device is attached to a pachinko machine, it is vertically fixed to the free end inside the front frame of the pachinko machine with the heel member facing the body frame side, and the heel member is locked at the corresponding position inside the body frame. A receiving bracket for fixing is fixed. Usually, the front frame of the pachinko machine is attached with a hinge at the left end portion, so that a locking device is attached at the free end on the right side. And the receiving metal fitting fixed to the inner side of the main body frame enters the inner side from the edge by the thickness of the main body frame (a plate material of about 20 mm), and the cylinder lock is disposed at the rightmost edge of the front frame. Therefore, the locking device is attached with the base frame body having an L-shaped cross section with the inside facing the free end side of the front frame.

  The front frame, which is attached to the main body frame so as to be openable and closable via a hinge, is normally closed without a gap due to the engagement between the upper and lower flange members of the locking device and the receiving metal fitting on the main body frame side, and is in a locked state. However, a gap may be generated between the closed front frame and the main body frame for some reason such as deformation of the main body frame or the front frame.
