PROBLEM TO BE SOLVED: To provide a wheel for a cargo handling vehicle capable of withstanding a load of several hundred kilograms.SOLUTION: A wheel for a cargo handling vehicle includes: a cargo placement part on which a cargo is placed; an operation part where an operator performs a steering operation and a lifting operation; a lifting device for lifting the cargo placement part; and a wheel 34 for causing the cargo placement part to be moved. The wheel 34 consists of a bearing 60 rotatably supported by an axle 30 and a tire 63 integrally formed of thermoplastic elastomer fitted to the outside of the bearing 60. Rubber strength of the tire 63 is 50-60D in Shore D (durometer type D), and the impact resilience is 65-55%.
