PROBLEM TO BE SOLVED: To reduce wheel vibration or a shock upon a collision and facilitate sideways rolling over a step, in a wheel with rotors designed for travel in all directions. SOLUTION: Each rotor 10 is rotatably supported about a rotation axis X1 across a radial direction from an axle 1, and is shaped so that a smaller diameter of a tip end 12 than the diameter of a base end 11 causes a periphery 19 to form an arc of a wheel periphery circle C1. A head shaft 32 projected upward from an upper end of a fork 7 supporting the axle 1 from both sides is supported in a cylindrical bearing portion 30 mounted on a vehicle body, rotatably about a vertical axis via an annular elastic body 35 encircling the head shaft 32.
