SEALING METHOD

摘要

A sealing method for a fastening structure where two members are fastened together, a sealing method for a fixing structure where an article is fixed to a fixing member, and a sealing method facilitates sealing. In a sealing method for a fastening structure, a through hole (11a) is formed in a bracket (11) to fix the bracket to a body (10). A bolt (2) is inserted in the through hole (11a), and one end of the bolt (2) passed through the through hole (11a) is fixed to the body (10) side. The sealing method is formed from an expansible material and has a first step where a non-expansion body (non-foam body (4)) in a non-expansion state is installed in a fastening structure (1). The method has a second step where an expansion body (foam body (41)) is formed by expanding the non-expansion body (4) and the through hole (11a) is sealed by the expansion body (41).
