The stadium S is, for example, an all-weather dome stadium. It has a function of switching to a baseball ground B, a soccer ground F or the like according to the purpose.

As shown in FIG. 1, the movable stand 2 is provided with two bow-shaped ones as a whole, and as shown in FIG. 2, as shown in FIG. A stair-shaped spectator seat 22 disposed above the support frame 21, an access passage 23 disposed at the front or middle of the spectator seat 22, and a fence disposed in front of the support frame 21. Rubber mat 24 and dugout 2
5, a photographer's seat 26, an entrance 27, and the like.

As shown in FIGS. 3 and 4, the rubber wheel 4 is mounted on a support leg 21a of a support frame 21 so as to support at least the entire weight of the unmanned moving stand 2. , And is made of solid urethane rubber.

The traversing drive means 5 generates an urging force for pressing the movable stand 2 against the inner peripheral surface of the fence 11 when the movable stand 2 moves. In the example of FIG. A fan or a blower is arranged on the inner side to generate a driving force in a transverse direction (outer direction) by blowing air inward.

The traveling drive source (traveling electric motor) 6
As shown in FIG. 2 and FIG. 4, a plurality of rubber wheels 4 are connected to a part of the plurality of rubber wheels 4. This is transmitted to some of the rubber wheels 4. Therefore, as shown in FIG. 5, the plurality of rubber wheels 4 are arranged in a state where the driving wheels a and the driven wheels b are dispersed.

As shown in FIGS. 2 and 3, the jack 7 is disposed on the support leg 21a of the support frame 21 and transmits the weight of the movable stand 2 to the ground floor 3 to thereby reduce the weight of the movable stand 2. This is to reduce the weight supporting burden of the rubber wheel 4 by supporting the weight increase by a spectator who is fixed or fully occupied, and a manual or electric jack is applied. Even in such a jack 7, as shown in FIG. 5, the jack 7 is arranged in a dispersed state under the support frame 21.

As shown in FIGS. 2 and 4, a plurality of side rollers 8 are provided so as to protrude outward from the support frame 21 of the movable stand 2 and move by contacting the inner peripheral surface of the fence 11. The stand 2 is kept in a certain close state to the fence 11.
