LOCK STRUCTURE

To provide a lock structure which can easily lock a first member to a second member, and hardly removes the locked first member from the second member by a simple structure.SOLUTION: A lock structure 1 has a first member 10 which comprises a lock claw part 20, and a second member 40 which comprises a penetration hole 42. In the lock structure 1, the second member 40 has a first face oriented to an insertion direction of the first member 10, and a second face arranged at a side opposite to the first face. A lock claw part 20 which is elastically deformable at least at a peripheral part of the penetration hole 42 has a claw main body part 21 in contact with the first face of the second member 40, and a protrusion 22 protruding to a removal direction of the first member 10 from the claw main body part 21. A recess 43 for inserting the protrusion 22 of the first member 10 into the first face of the second member 40 is formed in communication with the penetration hole 42.SELECTED DRAWING: Figure 1 【課題】簡単な構造で、第１部材を第２部材に係止させ易く且つ、係止状態の第１部材を第２部材から抜去させ難い係止構造を提供する。【解決手段】係止構造１は係止爪部２０を備える第１部材１０と、貫通孔４２を備える第２部材４０とを有する係止構造１で、第２部材４０は第１部材１０の挿入方向に向く第１面と、第１面の反対側に配される第２面とを有し、且つ、少なくとも貫通孔４２の周辺部が弾性変形可能な係止爪部２０は、第２部材４０の第１面に接触する爪本体部２１と爪本体部２１から第１部材１０の抜去方向に突出する突起部２２とを有し、第２部材４０の第１面に第１部材１０の突起部２２を挿入させる凹部４３が、貫通孔４２に連通して設けられている。【選択図】図１
