A switching valve that switches the traveling direction of the cleaning water sprayed from the jet nozzle from the internal direction of the throat pipe to the external direction of the throat pipe,
Furthermore, when the cleaning water sprayed from the jet nozzle and redirected to the outside of the throat pipe by the switching valve flows along the inner surface of the water tank, the inner surface of the water tank A flush toilet device characterized in that a resistance means for reducing the flow velocity flowing along is provided.   The resistance means is provided in the vicinity of the downstream side of the collision area where the main flow of washing water, which is injected from the jet nozzle and changed in the direction toward the outside of the throat pipe by the switching valve, collides with the inner surface of the water storage tank. The flush toilet apparatus according to claim 1.   The flush toilet apparatus according to claim 2, wherein the resistance means includes a bottom rib portion protruding upward from the bottom surface of the water storage tank.   The flush toilet apparatus according to claim 2 or 3, wherein the resistance means includes a side rib portion protruding inward from an inner side surface of the water storage tank. The flush toilet apparatus according to claim 3 , wherein the collision area is arranged so that the inner side surface and the bottom rib portion of the water storage tank surround the collision area in a plan view.   In a plan view, in the region surrounded by the inner side surface and the bottom rib portion of the water storage tank, the main flow of the wash water guided by the switching valve collides with the inner side surface of the water storage tank in an oblique direction, The area of the first region that is surrounded by the inner side surface and the bottom rib portion on the side where the washed water that has collided is inclined is larger than the area of the second region that is surrounded by the inner side surface and the bottom rib portion on the other side. The flush toilet apparatus according to claim 5, wherein the flush toilet apparatus is formed small. According to any one of claims 4 to 6 gap is provided between the side ribs protruding from the inner side to the inner side of the bottom rib and the water storage tank that protrudes from the bottom surface to above the water storage tank Flush toilet equipment.
