PURPOSE: To surely fix a face plate and prevent its slippage, deformation and flapping by putting the face bar between the upper plate and lower plate of a nearly I-shaped sectional mounting bracket fixed to a support member.

CONSTITUTION: An upper plate 12 and a lower plate 13 are horizontally protruded to both sides from the upper end and lower end of a vertical plate 11 to form a substantially I-shaped sectional bracket 10. Face plates B, B are nipped into a mounting part 1 formed of the upper plate 12 and lower plate 13 of the bracket 10, whereby the face plate B can be surely mounted and fixed, and the slippage, deformation and flapping of the face plate B can be prevented. Fixing parts 14, 14 protruded sideways from the lower plate 13 are fixed to a support member such as a rafter T by nailing, whereby the bracket 10 is fixed. When a locking part is protruded inward on the upper plate 12 or lower plate 13, the locking part is bitten into the face plate B, and the face plate B can be more surely fixed.
