PROBLEM TO BE SOLVED: To provide a scaffolding board bearing which facilitates and simplifies setting and dismantling of scaffolding. SOLUTION: This scaffolding board bearing is constituted of a hollow aluminum extruded bar 8 having an almost rectangular cross section, and a cubic cylindrical base member 9 being slidably fitted onto the bar 9. Right and left sidewalls 8a of the bar 8 each have a guide groove 15 extending in the longitudinal direction of the bar, into which a head 13a of a bolt 13 is movably fitted, and a non slip portion 16 for fixing the head 13a of the bolt 13 but allowing penetration of the male portion of the bolt 13, is formed at an opening edge of the guide groove 15. The head 13a of the bolt 13 which penetrates through each of right and left sidewalls 9a of the base member 9 is fitted into the guide groove 15, and the base member 9 is fixed to the bar 8 by means of the bolts 13 and nuts 14.
