PROBLEM TO BE SOLVED: To securely attach a sensor to a game ball pathway member. SOLUTION: The game ball pathway member 25 has a fitting groove part 251 penetrating in the front/rear direction and permitting insertion of the sensor 26 from front, and a pair of left and right engagement pawls 252 abutting on the rear of the sensor 26 inserted into the fitting groove part 251 to prevent backward movement of the sensor 26. The sensor 26 is fixed to the game ball pathway member 25 by fixing an ornament panel 28 to close the front face of the fitting groove part 251, into which the sensor 26 is inserted, to the front face of the game ball pathway member 25.
