れる。2. Description of the Related Art As shown in FIG.
A duct 2 made of synthetic resin protrudes from the case (2), and a duct 3 made of synthetic resin is connected to the duct 2. As shown in FIG. 6, on the outer peripheral surface of the duct 2, a plurality of claw portions 21 each having an inclined surface 22 inclined forward in the front end are formed at intervals on the side. An engagement hole 31 with which the engagement is made is formed. And duct 2 to duct 3
The two ducts 2 and 3 are connected by fitting the claw portions 21 into the engagement holes 31 while fitting the end portions into the end portions of the two ducts. The diameter of the duct 3 is larger than the diameter of the duct 2 to the extent that a gap is formed between the inner surface of the duct 3 and the outer peripheral surface of the duct 2 in the duct-coupled state. A seal member 4 such as a sponge is attached to the outer peripheral surface of the duct 2 so as to come into contact with the inner surface of the duct 3 when the duct 2 is connected. The other end of the duct 3 is connected to an outlet or another duct.

る。Means for Solving the Problems According to the present invention, a claw portion 21 whose front end is inclined forward is provided on the outer peripheral surface of one duct 2,
The other duct 3 is formed with an engagement hole 31 with which the claw 21 is engaged, and the two ducts 2 and 3 are connected by the engagement of the claw 21 and the engagement hole 31. , Characterized in that one side end of the claw portion 21 is formed as an inclined surface 24 that is inclined sideways. According to the above configuration, the other duct 3 is pivoted around the one duct 2 from the duct connection state.
Is rotated, the claw portion 21 is guided by the inclined surface 24 and sneaks into the duct 3. Therefore, the duct 3 can be removed later by pulling the duct 3 in the axial direction of the duct 2.

Therefore, only this difference will be described here, and other configurations will be described. Description is omitted. As shown in FIGS. 1 and 2, at one side end of the claw portion 21 of the duct 2, an inclined surface 24 that is inclined laterally is formed. The inclined surface 24 is continuous from the outer peripheral surface of the duct 2 to the upper surface of the claw portion 21. The inclined surface 24 of each claw portion 21 is located at the same side end. The engagement hole 31 of the duct 3 has a size including the inclined surface 24.

ることがない。According to the duct connection structure of the present invention,
Ducts can be easily connected by simply pushing one duct axially into the other duct, just as in the past, and even if it is necessary to remove the duct, one duct can be connected to the other duct. This can be easily done by slightly rotating the duct in the circumferential direction and pulling it in the axial direction. Moreover, since the claw portion has a vertical surface in the axial direction and a vertical surface on the other side end in the circumferential direction, the duct does not come off accidentally.
