  Further, the base may be provided only on the outdoor side. Thereby, when inserting a cylindrical part into a pipe, since a collar part will fall in the direction which does not have the said base part, it can prevent that the said base part and the said collar part overlap, and the said pipe | tube to a pipe can be prevented. There is an effect that the insertion force of the shaped portion is reduced.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

(Embodiment 1)
As shown in FIGS. 1-4, it formed eccentrically with respect to the cylindrical part 6 attached to the wall 16 or the pipe 16 provided in the ceiling (not shown) so that the indoor 17 and the outdoor 15 may be connected. On the outer periphery of the indoor side opening 7 of the cylindrical portion 6 and the cylindrical portion 6 having the setting ring 4 having the base 3 formed on the periphery of the collar portion 2 and the cylindrical portion 6, the wiring holding groove 5. The main body frame 1 is provided with a flange portion 8 formed in a substantially square shape projecting in the radial direction, and a rear surface side around the flange portion 8, that is, a rising portion 9 formed on a wall surface 18. The shape portion 6 and the setting ring 4 are integrally formed at the base portion 3, and a slit 12 is provided at a location where the setting ring 4 comes into contact with the wiring holding groove 5.

  As a result, when the cylindrical portion 6 is inserted into the pipe 16, the collar portion 2 falls to the indoor 17 side while the base portion 3 is fixed to the cylindrical portion 6, and the setting ring 4 is inside the pipe 16. Therefore, even if the setting ring 4 having elasticity (Shore A hardness: 40 degrees to 65 degrees) having the collar portion 2 is inserted into the pipe 16, it is possible to prevent a decrease in hermeticity.

  Further, the width of the slit 12 of the setting ring 4 is made narrower at the outer peripheral side opening 13 which is the outer peripheral side than the central side opening 14 which is the central side.

  The cylindrical portion 6 has a structure in which a motor 10 is provided, and power is supplied to the motor 10 by a wire 11. The wire 11 is accommodated inside the collar portion 2 of the setting ring 4, thereby holding the wire. It is assembled along the groove 5.

  As a result, the wiring 11 is inserted toward the outer peripheral side opening 13 which is a narrow space on the outer peripheral side of the slit 12 and is stored in the wiring holding groove 5. Without damaging the workability stored in the groove 5, the holding force of the wiring 11 can be improved, that is, the ventilation device can be assembled without the wiring 11 being lifted from the wiring holding groove 5. When the wire is inserted, it is possible to prevent the wiring 11 from being damaged due to contact with the end portion (not shown) of the pipe 16.

  For example, by setting the outer peripheral side opening 13 to about 2 mm and the center side opening 14 to about 4 mm, the workability is good when using the wiring 11 having an outer diameter of φ5 mm, and a structure that does not easily come off can be obtained.

  Further, only the collar portion 2 around the slit 12 is, for example, about twice the thickness of the other portion.

  Thereby, since the hardness of only the flange part around the slit 12 increases, the resistance at the time of insertion into the pipe 16 does not increase, and the holding power of the wiring 11 can be improved while maintaining the workability.

  The base 3 is provided only on the outdoor 15 side.

  Thereby, when inserting the cylindrical part 6 into the pipe 16, since the collar part 2 falls down in the direction where the said base part 3 does not exist, the said base part 3 and the said collar part 2 do not overlap, Therefore The said pipe | tube to the pipe 16 is not overlapped. The insertion force of the shape part 6 can be reduced.

  The ventilator according to the present invention can prevent deterioration in airtightness even when a resilient setting ring having a collar is inserted into a pipe. This is useful as an air conditioner or the like that is connected to a duct or the like that communicates with a room and ventilates the room.
