PROBLEM TO BE SOLVED: To provide a mounting structure of an arm member, which facilitates a work of putting on and taking off the arm member in the case of mounting it to a predetermined position such as at partitions or the like and also which has a larger mounting strength and wherein a posture of arm is made stable. SOLUTION: This is the mounting structure of the arm member, consisting of an arm member 1 to be mounted on a predetermined position such as at the partitions or the like and a cap piece 100 which, installed at this predetermined position beforehand, makes a mounting pedestal of the arm member 1. The arm member has a shaft part, an arm installed at the tip end side of this shaft part, and an anchor part 30 installed at the end side of this shaft part, and the cap piece 100 has an insertion part 141' to insert the base end side of the shaft part, a falling-off prevention part to prevent the anchor part 30 on the base end side from falling off, and an installation part installed at predetermined surroundings of the insertion part 141'. Then, a locking part is locked at the anchor part and makes a falling-off prevention by inserting the base end side of the shaft part into the insertion part and by making a rotating operation up to a predetermined angle position, having this shaft part as an axis. In this case, the arm is supported in a state of an under-support wherein the arm is in the state of being put on the installation part of the cap piece.
