Therefore, abrasion of the flexible conductor 44 can be suppressed as compared with the case where the second inclined surface 78B is not provided. Therefore, durability of the connector 10 can be improved.
  • the bulging portion 102 overlaps the recessed portion 78 when viewed from a direction orthogonal to the direction in which the pair of side walls 26, 26 face each other and the first direction. Therefore, when the flexible conductor 44 swings, the connector housing 16 has a section in which the flexible conductor 44 can enter both the bulging portion 102 and the recessed portion 78 in the first direction. Therefore, it is possible to suppress wear of the flexible conductor 44 due to contact with the connector housing 16 . As a result, the durability of the connector 10 can be improved.
  • the flexible conductor 44 is arranged between the bulging portion 102 and the recessed portion 78 when viewed from the direction in which the pair of side walls 26, 26 face each other. Flexible conductor 44 is sandwiched between bulging portion 102 and recessed portion 78 . Therefore, even if the flexible conductor 44 swings toward either the bulging portion 102 side or the recessed portion 78 side, the contact of the flexible conductor 44 with the connector housing 16 can be suppressed. Therefore, durability of the connector 10 can be improved.
