PROBLEM TO BE SOLVED: To provide a hug pillow which gives a sense of security.SOLUTION: A plurality of directivity parts 9 positioning apart along circumferential direction of a balloon 5 is provided along a meridian which connects end portions in the longitudinal direction of the balloon 5. A hug pillow has directivity in the expansion direction by the directivity parts 9 when air is supplied to the balloon 5. For example, by thickening the thickness of the directivity parts 9 and thinning the thickness of the parts between the directivity parts 9, the quantity of expansion/contraction is bigger in the radial direction of the balloon 5. The directivity parts 9 also include a function for maintaining a regular shape when the balloon 5 shrinks. |
