PROBLEM TO BE SOLVED: To perform the entrance and exit of air in a funerary space not to dew-condensate bones by attaching a funerary cover communicating with the funerary space, and forming a ventilation opening in the funerary cover. SOLUTION: In a tomb in a state where a lower base 2 and an incense burner 7 is mounted on a base 1, a funerary passage in which the lower base 2 is passed from the incense burner 7 to be introduced to a funerary space 10 is provided. The funerary passage is inclined, and bones put in a funerary opening naturally slide to fall in the funerary space 10. When a funerary cover 13 is removed, the funerary opening is opened. In the case where the funerary cover 13 is attached to the funerary opening, a plate spring abuts on the inner periphery of the funerary opening to display spring force, and is not slipped off simply. In addition, a flange is larger than the inside diameter of the funerary opening, and positioned to strike on the surface of the incense burner 7. Furthermore, the front of the funerary cover 13 has a net being a ventilation opening, the air can go in and out from the net, and the funerary space 10 is ventilated.
