    • PROBLEM TO BE SOLVED: To provide an armrest which securely holds an armrest pad at a certain angle.
      SOLUTION: When the armrest pad 124 is rotated to release the fitting between a protruded portion 118 of a plate 116 and a recessed portion 114 of a selector plate 110, the selector plate 110 is elastically deformed. The deformation of the selector plate 110 accumulates elastic force at the selector plate 110, so that arrival of the protruded portion 118 of the plate 116 at the recessed portion 114 of the selector plate 110 makes the selector plate 110 restore and makes the protruded portion 118 fit to the recessed portion 114 to stop the rotation of the arm pad 124. Therefore, holding force for holding a fitted state of the protruded portion 118 to the recessed portion 114 is increased. And the armrest pad 124 in a state where the elbow is put thereon has no possibility of unexpected rotation.
