PROBLEM TO BE SOLVED: To move a movable carriage substantially in any optional direction while being inexpensive. SOLUTION: This omnidirectionally movable carriage is provided with an operation handle 4 gripped by an operator, two omnidirectionally movable wheels 2a, 2b capable of individually imparting driving force and at least one universal wheel 3. Since driving wheels are only two pieces of the omnidirectionally movable wheels, a cost can be reduced. A problem of operational stability due to only two pieces of the omnidirectionally movable wheels for driving, can be complemented by operation by the operator for gripping the operation handle. |
