Abstract: A connector includes an inner housing which holds a plurality of electric wires, an outer housing which accommodates the inner housing along a first direction, a fixing member which fixes the inner housing and the outer housing to each other and a convex portion which protrudes from one of an outer surface of the inner housing and an inner surface of the outer housing in the first direction. When the fixing member fixes the inner housing and the outer housing to each other, the convex portion abuts against the other of the outer surface of the inner housing and the inner surface of the outer housing so that a repulsive force is generated between the inner housing and the outer housing.

Abstract: A connector lock structure includes a first connector housing, a second connector housing which is fitted to the first connector housing, a flexible lock member which is frontwardly extended from the first connector housing along a connector fitting direction and which has an engagement portion provided at an end portion thereof, a latch member which is provided on the second connector housing and which is engaged with the engagement portion, an operating arm which upwardly protrudes from the end portion of the lock member and rearwardly extends and which has a operation portion provided at a rear end portion thereof, and a fulcrum projection which is provided on at least one of an outer wall face of the lock member and a bottom surface of the operating arm facing the outer wall face.
