摘要

PROBLEM TO BE SOLVED: To provide duct-connecting structure for air-conditioning and its connecting method for unnecessitating fixing by bolts and nuts when connecting a duct for air-conditioning to the inside of an instrument panel and surely preventing slipping of the duct from a prescribed portion inside the instrument panel. SOLUTION: This structure is for connecting the duct 10 for air-conditioning to a blowoff port 2 for air-conditioning air formed at an end part on an instrument panel 1 side in a cab of an autotruck. In the structure, a positioning pin 5 projecting from the instrument panel 1 to the duct 10 side and a hole 14 for receiving a pin formed in the vicinity of an end part on the blowoff port 2 side of the duct 10 to receive the pin 5 are provided. An outer diameter dimension Dp of the pin 5 is set to be larger than an inner diameter dimension Dd of the hole 14. COPYRIGHT: (C)2006,JPO&NCIPI
