CONNECTOR

To provide a connector capable of effectively suppressing excessive displacement of a lock arm caused by an external force, while suppressing an increase of the manufacturing cost.SOLUTION: A lock arm 31 includes a locking projection 51 formed at a rear side in a fitting direction in a swingable arm 33 and protruding toward both sides thereof. A housing body 21 includes a protective wall 41 provided upright along both sides of the lock arm 31. The protective wall 41 includes a turn-up preventing projection 52 projecting toward a swingable arm 33 and provided such that the locking projection 51 and the turn-up preventing projection 52 overlap each other in a direction in which the swingable arm 33 swings at a side opposite to the housing body 21 with respect to the locking projection 51. With respect to the fitting direction, a front end surface 51a of the locking projection 51 and a front end surface 52a of the turn-up preventing projection 52 are flush with each other and a rear end surface 51b of the locking projection 51 and a rear end surface 52b of the turn-up preventing projection 52 are flush with each other.SELECTED DRAWING: Figure 6 【課題】製造コストの嵩張りを抑えつつ、外力によるロックアームの過度な変位を効果的に抑制することが可能なコネクタを提供すること。【解決手段】ロックアーム３１は、揺動アーム３３における嵌合方向の後方側に形成されて両側方へ向かって突設された係止突起５１を備え、ハウジング本体２１は、ロックアーム３１の両側に沿って立設された保護壁４１を有し、保護壁４１は、揺動アーム３３へ向かって突設されて係止突起５１に対してハウジング本体２１と反対側で揺動アーム３３の揺動方向に重なり合う位置に形成されためくれ防止突起５２を有し、係止突起５１とめくれ防止突起５２の嵌合方向の前端面５１ａ，５２ａ及び後端面５１ｂ，５２ｂがそれぞれ面一とされている。【選択図】図６
