PROBLEM TO BE SOLVED: To provide a decorative-chain mounting implement for a down pipe, which prevents an outsider from intruding onto an upper floor along a decorative chain. SOLUTION: This decorative-chain mounting implement 11 for the down pipe comprises a main body portion 20 which is to be inserted into the down pipe 12, and a hanging implement 21 for hanging the decorative chain 13. The main body portion 20 is formed in a cylindrical shape; its lower end is provided with a flange 20a; and a pair of groove portions 20c with a vertical rectangular cross section is provided in the state of facing an inside surface 20b. A pair of recesses 20e is provided in an intermediate part between the pair of groove portions 20c at an upper end 20d. The hanging implement 21 is formed in a funnel shape; two opposed points 21b at the peripheral edge of a lower end 21a on the side of a narrow mouth are connected together via a connecting rod 21c, so as to serve as a locking portion 21d of the decorative chain 13. An upper end 21e on the wide-mouth side of the hanging implement 21 is equipped with a flange 21f, and a pair of protrusions 21g is provided in opposed positions on the flange 21f. The protrusion 21g of the hanging implement 21 is locked to the recess 20e after being inserted into the main body portion 20 along the groove 20c. COPYRIGHT: (C)2008,JPO&INPIT
