PURPOSE: A toilet seat with a rack gear for automatic flushing by the load applied to a water tank type toilet is provided to prevent current leak and a flushing error and to obtain a simple structure and high assemblability. CONSTITUTION: A toilet seat with a rack gear for automatic flushing by the load applied to a water tank type toilet comprises an operation guide unit(100) and a flush operation unit(200). The operation guide unit leads a power transmission gear(220) of the flush operation unit to idle and engage with a rack gear(120) when the toilet seat(10) presses a seat spring(130) by the load of a user and moves to the upside of a toilet body. The flush operation unit restores the toilet seat by the restoring force of the seat spring when the user leaves the toilet seat, opens a drainage as a siphon cover is turned upward by a flush wire pulled with a wire roller(240) rotated according to the rotation of the power transmission gear engaged with the rack gear, and flushes the toilet by discharging cleaning water stored in a tank through the opened drainage.
