To prevent a detection switch and a connector for the detection switch mounted to the detection switch from removing against intention of a mounting operator.
In a prize winning device 20 of a Pachinko machine 1, a locking piece 50 locks the detection switch 40 and also the connector 41 for the detection switch. The mounting operator thus does not need to pay excessive attention against the removal of the connector 41 for the detection switch. The removal prevention of the connector 41 is enabled by improving only a part of a structure of the locking piece of a conventional detection switch 40 removal preventing mechanism, so that a new dedicated component is not required to be disposed. The removal can be prevented regardless of removal easiness of the connector 41, so that selection ranges of the detection switch 40 and the connector 41 can be increased.
