Claims

[Scope of utility model registration request]

A cylindrical elastic duct is arranged between the wind outlet at the front end of the case and the front end opening of the fixed duct inside the case, the rear end is connected to the front end opening of the fixed duct, and a ring-shaped coil made of shape memory alloy is installed at the front end. , and is supported radially by multiple coil springs made of ordinary spring material, and a coil made of shape memory alloy is wound in a ring shape around the middle part of the coil spring. An air blowing switching device for a vehicle, which is supported radially and reduces the diameter of a front end coil and a middle coil when energized so that blowing air can be concentrated and diffused.
