A cart that reduces impact on a load placed on a loading platform 50. The cart 10 includes a drive that raises/lowers the platform 50 by rotating a motor which extends/retracts a mechanism 70 vertically. The drive rotates the motor when an external force raises/lowers the platform 50 and extends/retracts the mechanism 70. When a control device detects lowering of the platform 50 held at a predetermined vertical position and detects an increase in weight of the load on the platform 50 based on an output signal of a rotation sensor that detects rotation of the motor and an output signal of a current sensor that detects a drive current of the motor, the control device controls the motor such that the platform 50 is raised and held at the either the predetermined vertical position or a vertical position lower than that position.
