PROBLEM TO BE SOLVED: To provide a pallet lock device provided with a lock bar capable of surely pressing pallets of different size. SOLUTION: The lock bar 21 of the pallet lock device is provided with a widening part 60 in a head part 50 turning around a horizontal shaft. With this structure, when the head part 50 is pressed to the pallet, while turning, the head part 50 and the widening part 60 are brought in contact with the pallet. Pallets of different size can be surely pressed, while preventing the widening part 60 from fitting in a grid hole of the resin pallet, by extending the widening part 60 along the horizontal axis.
