PROBLEM TO BE SOLVED: To provide an elbow measuring implement which enables an elbow with a necessary length to be easily measured on a construction site. SOLUTION: In this elbow measuring implement, a tubular drain member 2, the upper end of which is detachably tube-fitted into the drain tube part of a lower part of a drain, and a tubular down-pipe member 5, the lower end of which is detachably tube-fitted into the upper end of a down pipe, are connected together by means of a windable strip-shaped measure (convex 7) with a returning force. Furthermore, one end of a tubular body 1 bent in an L-shape serves as the tubular drain member 2, and the other end thereof serves as a convex engaging part 3. One end of another tubular body 4 bent in an L-shape serves as the tubular down-pipe member 5, and the other end thereof serves as a convex engaging part 6. The tubular drain member 2 and the tubular down-pipe member 5 are connected together by means of the convex 7. COPYRIGHT: (C)2007,JPO&INPIT
