摘要

PROBLEM TO BE SOLVED: To make compatible basic structures of a casing separated ventilation device and a casing integrated ventilation device.SOLUTION: An upper casing separated ventilation device 9 includes a basic structure 10 and an attachment 20. The basic structure 10 includes a body 11 and an opening/closing mechanism 17. The body 11 includes: a suction part 12 for sucking and supporting a plate body of a sash; an indoor-side wall part 13 with which a vent hole 13a is formed; indoor-side connected parts 18a and 18b; and an outdoor-side connected part 18c. The attachment 20 includes: a closing part 22; and an insertion part 21 that protrudes upwards from the closing part 22 and is inserted into a recessed groove part of an upper casing. The closing part 22 includes a passage forming wall portion 22b that covers the opening/closing mechanism 17 and defines a ventilation passage 16. The attachment 20 connects indoor-side connecting parts 25a and 25b and an outdoor-side connecting part 25c to the indoor-side connected parts 18a and 18b and the outdoor-side connected part 18c of the body 11. The basic structure 10 may also be available for an upper casing integrated ventilation device.
