PURPOSE: A leak preventing cover of a roll brush module is provided to change the flowing direction of fluid vertical to a driving axis and scatter the fluid, thereby preventing the fluid from being inserted into a driving unit. CONSTITUTION: A leak preventing cover of a roll brush module includes a body portion(1) and a direction changing portion(3). The body portion is fixed to an external driving axis of a support panel. The body portion is rotated with the support panel. The direction changing portion is located on a surface of the body portion which faces a flowing direction of fluid. The direction changing portion scatters the fluid in a direction orthogonal to the driving axis. |
