A hand truck includes a support base, a plurality of wheels connected rotatably to the support base, a handle unit connected to the support base, and a fork unit. The support base has a pair of holding portions and a recess portion disposed between the holding portions. The fork unit has a pivoting portion connected pivotally to the support base, an inserting portion opposite to the pivoting portion, and a connecting portion interconnecting the pivoting portion and the inserting portion. The fork unit is pivotable between a retracted position, where the inserting portion and the connecting portion are adjacent to the support base, and a projected position, where the inserting portion and the connecting portion are away from the support base.
