[Constitution] A state in which a pillow core is formed of an elastic body having a large number of open cells, the pillow core is sealed with an airtight airtight cover, and outside air enters the open cells of the elastic body. A check valve is provided for switching the open cell to a state in which the open cell is blocked from the outside air, and when the valve element of the check valve is pressed inward of the pillow, air is supplied to the open cell of the elastic body. It is configured such that the elastic body expands and the pillow height increases.

[A] When the valve body of the check valve is pressed inward of the pillow, the outside air passes through the check valve and enters the open cells of the elastic body, so that the elastic body expands and the height of the pillow rises. Get higher. In this state, when the valve body of the check valve is pressed and the pillow is compressed little by little, the air in the open cells of the elastic body is discharged out of the pillow through the check valve with this, and the elastic body contracts. The height of the pillow gradually decreases. As the pillow keeps compressing, the height of the pillow will be the lowest.

[B] When the valve body of the check valve is pressed little by little while the height of the pillow is the lowest, air enters the open cells of the elastic body through the check valve, and the elastic body expands. The height of the pillow gradually increases.

[C] From the state where the height of the pillow is increased as in [A] above, the valve body of the check valve is pressed and the pillow is gradually compressed, or as in [B] above. When the height of the pillow is lowered, the inverted body is pressed little by little, and when the height of the pillow is at the desired height, the pressing of the valve body of the check valve is released. External air does not flow in and out, and the height of the elastic body becomes constant, so that the height of the pillow can be set to the desired height.

[D] Since the height of the pillow can be changed and adjusted as described above, the air is supplied into the pillow by, for example, repeatedly squeezing a rubber spherical air pump to change the height. Compared to the case of adjusting, the height change adjustment does not take much time and effort.

[Effect] Accordingly, a pillow whose height can be changed and adjusted easily and in a short time can be provided.

The configuration, operation and effect of the invention according to claim 2 are as follows.

[Structure] A pillow core member is formed by a pillow core member made of a predetermined material and a plurality of blocks whose size can be adjusted. The block body has an elasticity provided with a large number of open cells. A check valve that closes the body with an airtight airtight cover and switches between a state in which outside air enters the open cells of the elastic body and a state in which the open cells are shut off from the outside air is provided. When the valve body of the stop valve is pressed inward of the pillow, air enters into the continuous cells of the elastic body, the elastic body expands, and the pillow height is increased.

[Effects] [E] Actions [A], [B],
The same operation as [c] and [d] can be obtained, and the following operation can be obtained.

[F] Since a plurality of block bodies having the above-mentioned configuration are provided, the height of the block bodies can be changed for each block body, whereby the height change of the pillow is partially adjusted. For example, the pillow can be deformed concavely to fit the head.

[Effect] Therefore, in addition to the same effect as the effect of the configuration of claim 1, a pillow that can be felt comfortable by many people can be provided. .
