# Joint structure

## Abstract

A second member has a through-portion penetrating toward a first member. An overlapped surface of the second member with the first member includes a recess. The recess is recessed so as to surround an entire periphery of the through-portion. The recess is provided with a sealing material. The sealing material closes a gap between overlapped surfaces of the first member and the second member.
