PROBLEM TO BE SOLVED: To effectively utilize light rays of a light source by devising a driving force transmission component so as not to shield light from a light source in order to express and report condition changes such as the change of a game state on a game board surface and visually express the state change of the movable board surface component corresponding to the progress of game contents. SOLUTION: The movable board surface component unit comprises: a movable board surface component 20 arranged on a game board surface or inside an opening formed on a game board and operated along a prescribed track; a motor 31 as the drive source of the movable board surface component; transmission members 33 and 34 which transmit the rotary driving force of the motor to the movable board surface component, are operated together with the movable board surface component and comprise a non-translucent and low frictional resistance material; and the light source disposed on the back surface side of the transmission members to illuminate the front. A translucent part 35 is formed at the part of the transmission members to be irradiated with emitted light from the light source when the transmission members are on the optical path of the emitted light.
