ON-ROOF FIXTURE

PROBLEM TO BE SOLVED: To provide an on-roof fixture capable of stably fixing and keeping itself on a wavy roof by preventing a space between gripping pieces from being widened.SOLUTION: In an on-roof fixture A, two gripping members 10 are connected to each other with their gripping pieces 13 opposing each other, and leg pieces 12 are tightened to each other so that the gripping pieces 13 are located adjacent to each other to grip and fix a bolt body B protruded from an apex part Y1a of a wavy roof Y. Each gripping member 10 includes a guide protruded piece 10a, and a through opening part 10b integrated therewith and having a size allowing the guide protruded piece 10a to be inserted therethrough. The guide protruded piece 10a and the through opening part 10b of the gripping member 10 are male-female joined to each other to connect the two gripping members 10 to each other. The gripping piece 13 includes a locking part (a bolt locking groove part 13b) for locking a male screw part B1 of the bolt body B, and a fastening protruded piece 14.
