An overspeed braking mechanism for a stairlift includes: a main shaft driven by a motor to rotate; a claw member connecting with the main shaft to thereby rotate synchronously with the main shaft and having a tooth; a cam member connecting with the claw member and having an abutting portion spaced apart from the tooth of the claw member radially by a predetermined angle; a driven unit having a cam contact portion, wherein the abutting portion of the cam member abuts against the cam contact portion to cause the driven unit to swing, whereas a pawl portion of a claw contact member engages with the tooth of the claw member and has a switch contact portion; and a micro switch adapted to be touched by the switch contact portion, controlling the motor to drive the main shaft to rotate.
