The cap means and the float are not mutually fixed, and the hitting means includes: stoppers formed at a lower portion of the float and an upper portion of the cap means to be hit and caught when the float is moved upward; and a caught bar extending from the float to the stopper and caught in the stopper from a lower portion of the float when the float is moved upward. The trap includes a lifting control means controlling rising and lowering of the float by magnetic force, and can easily discharge condensate by easily ...
