The operation of the above technical means is as follows. That is, even if another object such as a vacuum cleaner comes into contact with the protruding corner, the rotating body is provided at the contact portion, so that the rotation of the rotating body can alleviate the impact due to the contact of the other object to some extent. it can. In addition, when the cords of the vacuum cleaner move in sliding contact with the protruding corner, the rotating body is located at the protruding corner, so that the contact surface also rotates with the movement of the cords. And the sliding contact of the cords with the protruding corner can be avoided as much as possible.

[0006]

According to the present invention, therefore, when a contact is made with another object at the corner of the structure, the rotating body that becomes a part of the corner or the object on the side that comes into contact therewith is not deformed. Easy to avoid damage. Further, there is an advantage that the sliding contact of another object with the projected corner can be suppressed as much as possible, and the occurrence of dirt on the projected corner due to the sliding contact can be effectively suppressed. According to the protection device of the second aspect, it is possible to protect the portion of the room that is most likely to come into contact with another object with good appearance. In the protection device according to the third aspect, it is possible to effectively protect a portion at a narrow entrance and exit, which is easily contacted with other objects such as a vacuum cleaner or cords. In the protection device according to the fourth aspect, the base and the rotating body fixed to the structure are factory-produced before being attached to a portion where the structure is to be attached, and these are integrally handled as a set. Therefore, for example, as compared with the case where the supporting portions of the rotating body are separately formed at each of the locations where the structure is to be mounted and at both ends of the rotating body, there is no need for troublesome work, and workability is reduced. Is advantageous.
