Abstract
A game machine operation device wherein a first grip section and a second grip section have their outer sides curved into the shape of an arc, with the curved surfaces serving as guide sections along which the operator can move his palms. Therefore, the operator is capable of placing his hands or fingers used for operating the device in a comfortable position on the first and second grip sections and freely move his hands or fingers along the curved surfaces. In conventional game machine operation devices, the grip sections are formed so as to extend vertically downward, which prevents the operator from changing the position of his hands, depending on his hand size, so that an operator with large hands cannot operate the operation device easily, causing him to get tired hands or fingers.
