To provide a handrail unit capable of adjusting the positions of a vertical handrail and a horizontal handrail, attaining miniaturization, weight reduction, thinning and cost reduction of constitution as the handrail unit to simplify installation work to an installation object or place and moreover making position adjustment freely as the position adjustment range of the vertical handrail and horizontal handrail is sufficiently large.

The vertical handrail 8 and the horizontal handrail 7 are arranged in an alternately intersecting manner between rail members 1, 1 or 2, 2, facing each other in parallel in vertical and lateral directions, of a rail frame with the rail members 1 or 2 assembled in quadrangular shape from the front view. Both ends of the handrails 7, 8 are mounted in a slidable and position-fixable manner to the rail members 1 or 2 by handrail support members 4 or 40, and the rail frame is mounted to the object for installation.
