The present invention relates to a roller blind, comprising a control device (1) and a linkage assembly (2). The control device(1) comprises a reeling mechanism (11), a solenoid valve (12), a push mechanism (14), a front cap (15), and a damper. After the solenoid valve (12) is energized, the solenoid valve (12) drives the push mechanism (14) to push against the front cap (15) so as to separate the front cap (15) from an engaging portion of the reeling mechanism (11), and the reeling mechanism (11) is not subject to a resistance of the damper. A curtain fabric (A) is not affected by the resistance of the damper and can be quickly lowered by gravity.
