PILLOW

PROBLEM TO BE SOLVED: To provide comfortable sleep by stabilizing support of a neck or parietal region, not only in a supine position but also when lying on the side. SOLUTION: A neck side part 1 for supporting a neck side and a parietal region side part 10 for supporting a parietal region side are connected by a strap-like connecting member 20, and the neck side part 1 and the parietal region side part 10 are formed such that a cross-section in a vertical width direction A is an abbreviated ellipse which has top-bottom symmetry relative to center lines 2, 11 in the vertical width direction A. Each of the part 1 and part 10 is divided into center areas 1a, 10a in a horizontal width direction B, and into a pair of side areas 1b, 10b continuing on the left and right of the center areas 1a, 10a. Thicknesses of each area, that is, the thickness H1 of the center area 1a, thickness H2 of the side area 1b, thickness H3 of the side area 10b, and thickness H4 of the center area 10a are formed such that H1>H2>H3>H4. The thickness between upper and lower ridge lines 3, 12 stretching in the horizontal width direction B is similarly formed. A protrusion 4 protruding towards the parietal region side 10 is formed on the parietal region side 10 of the center area 1a, and a groove 13 for inserting the protrusion 4 is formed on the neck side 1 of the center area 10a.
