Abstract: A forklift having a pallet lock device. On an upper face of a top end of a lock bar to lock a pallet, a tapered portion is disposed. When a fork is inserted into the pallet, the tapered portion comes into contact with an end face of the pallet and the lock bar rotates downward. When a landing sensor is turned on by a magnet disposed on the lock bar, the lock bar is immediately driven and the locking operation is started. Then, the top end of the lock bar pushes or comes into pressure contact with an upper face of a lower deck board of the pallet, and the pallet is locked.
