The present invention can be applied not only to a grounding structure for a component member, but also to a grounding structure having a configuration in which a grounding member is pressed against a charging member to be electrically connected and grounded.

It is a front view which shows the pachinko machine which concerns on one Embodiment of this invention. It is a rear view which shows the pachinko machine concerning one embodiment of the present invention. It is the perspective view seen from the front side which shows the pachinko machine concerning one embodiment of the present invention. It is the perspective view seen from the front side which shows the state by which the glass frame and plate unit of the pachinko machine concerning one embodiment of the present invention were opened. It is a perspective view showing a ball passage unit provided with an earth structure concerning one embodiment of the present invention. It is a right view which shows the ball path unit provided with the earth structure which concerns on one Embodiment of this invention. It is a disassembled perspective view which shows the earth structure which concerns on one Embodiment of this invention. It is a right view which shows the decomposition | disassembly state of the earth structure which concerns on one Embodiment of this invention. (A) which shows the earth member which concerns on one Embodiment of this invention is a right view, (B) is a rear view. It is an expansion perspective view showing the state where the ball passage unit was attached to the inner frame concerning one embodiment of the present invention. It is a front view which shows the state by which the game board was attached to the inner frame which concerns on one Embodiment of this invention.
