Wire harness leading-out port structure of electric connection box

A wire harness leading-out port structure of an electric connection box, comprising:

• a first member and a second member to be coupled to each other,
• the coupled first member and second member having a wire harness leading-out opening formed at a junction between the first member and the second member, the wire harness leading-out opening being used for leading out a wire harness from an inside to an outside of the coupled first member and second member,
• the first member including a first half-cylindrical body around a periphery of the wire harness leading-out opening of the first member,
• the second member including a second half-cylindrical body around a periphery of the wire harness leading-out opening of the second member, wherein
• the first half-cylindrical body and the second half-cylindrical body are coupled to each other at both circumferential ends of the first and second half-cylindrical bodies so as to form a cylindrical wire harness leading-out guide for guiding the wire harness, and
• a concave portion for accommodating a loose portion of an armoring member wrapped around an outer circumference of the wire harness is formed in an inner circumference of a circumferential junction between peripheral walls of the first and second cylindrical bodies.
