A soundproof bracket 20 for closing the gap G between the movable partition walls 6 and 8 is provided on the upper and lower end surfaces of the movable partition walls 6 and 8, respectively. Each soundproof bracket 20 is capable of simultaneously performing soundproofing and its canceling operation at the same time through an operation rod 24 by an operation case 22 embedded and fixed in one of the left and right ends of each movable partition wall 6, 8. The operation by the operation case 22 is performed by rotating an operation handle 25 exposed to the outside of both surfaces of the movable partition wall 6.

As shown in FIGS. 2 to 4, each soundproof bracket 20 is provided inside the fixed bracket 26 and a long fixed bracket 26 having a U-shaped cross section that is fixed to the upper and lower end surfaces of the movable partition walls 6 and 8. It is basically composed of a long moving bracket 28 having a U-shaped cross section. A support shaft 30 is provided upright on the bottom surface of the fixed bracket 26 at intervals in the longitudinal direction, and an insertion hole 32 for inserting the support shaft 30 is formed in the bottom surface of the moving bracket 28 correspondingly. ing. Moving bracket
Prior to the mounting of 28, the spring member 34 is fitted and inserted into the support shaft 30,
This biases the moving bracket 28 outward. Further, the moving bracket 28 is detachably stopped after being mounted on the support shaft 30.
