PROBLEM TO BE SOLVED: To provide a lock device in which engagement strength between a hook and a pole does not vary.SOLUTION: A hook 157 and a pole 161 are engaged with each other by using a recess 157d that is located in parallel with a rotating axis of the hook 157 and in which a first stopper surface 157s intersecting with the rotating direction of the hook 157 and a second stopper surface 157t opposing to the first stopper surface 157s via a space are formed and a projection 161a of the pole 161 in which a first contact part 161s and a second contact part 161t enabling abutment on the first stopper surface 157s and the second stopper surface 157t of the recess 157d are formed. Each of the first stopper surface 157s and the second stopper surface 157t of the recess 157d has a planar shape, and each of the first contact part 161s and the second contact part 161t of the projection 161a has an arcuate planar shape. |
