A scrolling mechanism for a window shade is received in a tube and includes a housing, a wheel, a driving gear, a bevel gear unit, a first scrolling unit and a second scrolling unit. Two springs are respectively connected to the first scrolling unit and the second scrolling unit. The driving gear drives the first scrolling unit, the first scrolling unit drives the second scrolling unit. The torque generated by the scrolling mechanism balances the torque that is created by operation to the bottom rail of the shade so as to control the position of the shade.
