PROBLEM TO BE SOLVED: To provide a lever float type drain trap in which a float is prevented from being damaged.;SOLUTION: A cover body 4 is fastened to a body 3 having an inlet 1 and an outlet 2 to configure a casing which has a valve chest 6 therein. A first valve port 7 and a second valve port 8 which communicate the valve chest 6 with the outlet 2 are formed on a lower part of the valve chest 6. A lever 11 rotated around a swinging shaft 10 which is supported in the valve chest 6 is disposed. A float 12 which floats and lowers in accordance with the level of liquid in the valve chest 6 is connected to the lever 11, and a first valve element 18 and a second valve element 19 which open and close the first valve port 7 and the second valve port 8 are connected to the lever 11. A stopper member 20 on which the float 12 abuts when the lever 11 is further rotated in a valve-closing direction from a position where the first valve element 18 and the second valve element 19 close the first valve port 7 and the second valve port 8, is disposed below the float 12. The stopper member 20 is formed of a conical coil spring of which coil radius is enlarged toward the upper side.;COPYRIGHT: (C)2013,JPO&INPIT
