To provide a shelf unit for a wall face which can be easily fitted and of which the shelf board is hardly colapsed.

A tapered face 18 narrowed toward the basal end is formed in the middle of a support bar 3 attached to a sash 2. The support bar 3 pierces through a parallel hole 4 of shelf boards 5 in which the bar 3 is inserted, and a hole in which a female screw member 20 is embedded is formed to coinside with the position of the tapered face 18. By pressing the tapered face 18 of the support bar 3 by means of a set screw 19 screwed in the female screw member 20, the front end of the set screw 19 transfers to the basal end side of the support bar 3 along the tapered face 18 in accordance with the pressing force and the basal end face of the shelf board 5 is naturally pushed on the sash 2 and hence, the shelf board 5 can be fixed without shift.
