PROBLEM TO BE SOLVED: To provide a supporting structure by which the leg of a board fence can simply and easily be attached to and detached from the insertion hole of a supporter. SOLUTION: A slide member 37 is biased in the direction of projecting of its tip part 44 from the engaging hole 34 of a cylindrical body 32 and a protrusion 39 provided at the slide member is engaged with a first recess part 53 formed at an operation member 46 to support the leg part in a first state where only the inclined surfaces 42 and 43 of the tip part project from the engaging hole and in a second state where the protrusion is engaged with a recess part 54 formed at the operation member to make the engaging face 41 of the tip part project from the engaging hole from the inclined surface. In the second state, the leg part can be supported in the insertion hole of the holder in a state where it cannot be pulled out. By pushing the operation member from the second state, the state is converted to the first state to make it possible to pull the leg part from the insertion hole. |
