Referring to FIG. 2 , the expansion or compression direction of the stretchable unit 200 and the discharge direction of air through the discharge unit 400 according to an embodiment of the present invention will be described as follows.

Based on the three-dimensional Cartesian coordinate system of x-y-z, for example, when the virtual plane formed along the direction in which the expansion and contraction part 200 is expanded or compressed is called the x-y plane, the air is discharged from the discharge part 400 The direction may be a z-axis direction.

That is, the discharge unit 400 may be provided so that air is discharged in a vertical direction in the direction in which the expansion and contraction unit 200 is expanded or compressed.
