PROBLEM TO BE SOLVED: To provide a lock structure capable of preventing half lock and easily confirming whether it is complete lock or half lock.SOLUTION: A lock structure 1 comprises a lock protrusion 2 and a lock arm 3 including an elastic deformation piece 4 and a protruding portion 5 and being engaged to the lock protrusion 2. The lock protrusion 2 and the protruding portion 5 include opposite surfaces 20, 50 which are opposite to each other in an engaged state, and tapered surfaces 21, 51. On the tapered surface 21, a convex portion 6 is provided. On the tapered surface 51, a concave groove 7 is provided where the convex portion 6 is slid on a bottom face 7a. The bottom face 7a includes a first bottom face 71, a second bottom face 72 and a boundary part 73. The first bottom face 71 is tilted away from a surface of the elastic deformation piece 4 as approaching the boundary part 73. The second bottom face 72 is tilted closer to the surface of the elastic deformation piece 4 as separating from the boundary part 73. |
