<P>PROBLEM TO BE SOLVED: To provide a mailbox in which the mails are not viewed from a throw-in port with the use of a fiber scope, etc., mail theft by applying an adhesive to the distal end of wire, etc. is impossible, and also the accumulation state of the mails, etc. can be recognized only relevant people from outside. Ž<P>SOLUTION: When a substantially plate-like object 2 hanging from a part projected forward from the upper part of the front surface of a mailbox body is lowered, the window of the object is aligned with the window of the body front surface 4 in a front and rear direction, so as to generate a hollow to be the throw-in port. A posted matter from the hollow falls onto a seesaw board 9 having no gap between the board and an inner wall tightly adhering onto an object 10 which is extended from a ceiling having no gap between the ceiling and the inner wall when viewing from a front side. When a hand which hung the substantially plate-like object is lifted, the object is raised so as to eliminate the throw-in port. The posted matter falls onto a board 5, whose rear part is floated in the air, from the gap which is generated between the lowering seesaw board and the object extended from the ceiling without lowering. In this case, when the rear part is lowered, string shape substances 21 extended from the upper surface of the most rear part onto an obliquely rear base are pulled downward, and a state, where object 22 at the distal ends of the other string shape substances is raised, can be confirmed from outside through a transparent body 26.
