By
These parts could be bent or damaged.

Further, in the conventional connector coupling structure, when the first connector 3 is inserted into the mounting portion 1 such as a stay member of an automobile, an engaging pin 6B protruding from the rear end of the swing lever 6 is fitted. There is a need. When the first connector 3 is inserted into the holder 2 in this manner, the swing lever 6
Is a state in which it can freely swing, so that the operation of inserting the engagement pin 6B into the introduction portion 13A of the guide groove 13 requires skill, and there is a problem that the assembling operation is complicated.

An object of the present invention is to provide a low-cost connector support mechanism that can reduce the number of parts and reduce the size, and that can perform the assembling work smoothly and reliably. The point is to take such measures.
