PROBLEM TO BE SOLVED: To lock a screen door by one touch operation by attaching a lock body at a position corresponding to a fitting and inserting member at the time when the screen door is closed, releasing pinching of the fitting and inserting member of an elastic body incorporated into the lock body, and enabling the attaching and detaching of the fitting and inserting member. SOLUTION: A fitting and inserting member 5 is composed of a tapered edge part 5a and a screw part 5b with a metal-made or hard synthetic resin- made screw nail, and a groove 5c is drilled on the circumference of the fitting and inserting member 5 in the neighborhood of about 5 mm from the edge part 5a. The screw part 5b is attached to the opening and closing end of a screen door, and when the screen door is closed, the fitting and inserting member 5 is inserted in a lock body 4 from a fitting and inserting hole 10. When both the legs 15b of a spring 15 in which the tapered edge part 5a is opened in substantially parallel from a lever part advance while widening further, both the legs 15 of the spring is fitted to a groove 5c notched on the fitting and inserting member 5, which is sandwiched by a spring 5 to lock the screen door.
