PURPOSE: To easily and easily replaceably attach a sacrificial anode to a nonthread part by connecting the sacrificial anode member with free continuity to a supporting part installed in freely attachably and detachably at a sacrificial anode mounting part of a city water pipe, etc., laid under the ground. CONSTITUTION: When the sacrificial anode 12 consisting of a metal having larger corrosion inclination than iron such as Zn and Mg is attached by using a cap 3 of a saddle snap tap 2 mounted on a city water main pipe 1 as a sacrificial anode mounting part, a sacrificial anode attaching device 10 composed of a supporting member 11 fixed to the cap 3 and the sacrificial anode 12 attached thereto is used. The supporting member 11 is constituted from an enveloping body 13 which is made of a conductive metallic plate and is processed by a punching and bending, a male screw body 14 which is fixed and provided projectingly thereto and a cap 15 attached to the enveloping body 13. The sacrificial anode member 12 consisting of Zn, Mg, etc., is screwed in a female screw hole 20 fit to the male screw body 14 of the supporting member 11 and the cap 15 is attached to the enveloping body 13 by pressing. The sacrificial anode member 12 holds a good electrical conducting state with the cap 3, and further, can be simply replaced only by loosing the screw. |
