In a rotary table of a seat for automobiles, a bolt-coupled holder and an end of a push plate are rotated by being engaged with an end of a fixing plate fixed to the bottom of the automobile to reduce a noise caused by the rotation and sustain a shock occurring in a car accident. A projecting disc portion has a thruhole in the center of the fixing plate, fixing grooves with inner sides opened are formed along the border of the thruhole, the push plate coupled with the holder via coupling holes is formed with a fixing groove in front of the coupling holes in a central circular portion, locker fixing holes are formed in front of the fixing groove of the push plate, the holder coupled via the coupling holes along the outer side of a thruhole in the center has an abutment adjacent to the outer border, a fixing groove with outer side opened is formed into one side of the border to fix the border of the thruhole of the fixing plate between the push plate and outer border of the holder, a fixing plate with opposing projecting brackets is fixed via locker fixing holes of the push plate, a handle is installed to the projecting brackets by welding a fixing rod to a concave semi-circle and having a circular hole in the center for being inserted into the projecting brackets, and a locking device having a circular rod inserted into the circular hole of the projecting brackets fits a locking bracket and a spring into the circular rod.
