CONSTITUTION: A king pin 10 is rotatably connected to a camera dolly 7. An inclined axle 14 is connected to a king pin blade 12. A first wheel assembly 20 is provided with a half wheel 32 inside thereof. The half wheel 32 is rotatably fixed to an inclined axle 14 via ball bearings 34, 36. An outside half wheel 30 is secured to the half wheel 32. An air tire 24 is fixed to the half wheels 32, 30. A second wheel assembly 50 is constituted in the same manner. A tracking wheel 22 is stretched around a tracking wheel plate 44, has a ring 46 recessed at outer profile, and is connected to the half wheel 32. With the above- described configuration, the wheel unit can be used for a track and the ground. COPYRIGHT: (C)1990,JPO |
