PROBLEM TO BE SOLVED: To provide a baseboard for a scaffolding board which enables one-touch mounting and removal of a baseboard body. SOLUTION: A plurality of one-touch lock fittings 6 are provided on the outer surface side of the baseboard body 5. Each of the one-touch lock fittings 6 comprises a fixed frame 7 fixed to the baseboard body 5, an operating lever 8 whose lower end is pivoted to the fixed frame 7, a grip fitting 9 where a hook portion 10 for gripping a side bending part 1b of the scaffolding board 1 is formed in the lower part of a slide plate 9a vertically slidably supported by the fixed frame at a position below the operating lever 8 and projecting downward below the baseboard body 5, and a spring 11 interposed between the operating lever 8 and the grip fitting 9 so that, in the erected state of the operating lever 8, the grip fitting 9 is locked at a position where the hook portion 10 grips the side bending part 1b of the scaffolding board 1 and the tip 10o of the hook portion 10 comes into contact with the under surface of a top plate 1a of the scaffolding board 1 and that, when the operating lever 8 is rotated downward, the grip fitting 9 is slided downward to be unlocked.
