It cannot be lowered. However, in the stowed state (folded state), the seating surface becomes the seating surface gl2 when stowed, and the seating surface becomes relatively high. Therefore, there is a high need to raise the movable part g3 a to correspond to the higher seating surface. There is little need to lower the moving part g3a. Therefore, the control lever g9 is concealed in the storage state (folded state), and there is almost no problem even if the movable part g3a cannot be lowered. Is more important.
- the height of the armrest part g3 is the height of the seat when retracted. It can be a chair with an armrest function that is less than the height of the gl2 surface (ie without armrests). Such a chair without an armrest has an advantage that the user can sit on the chair not only from the front of the chair but also from the side of the chair (left and right sides).
- the armrest g3 is set higher than the leg resting part back surface 7 serving as the seating surface, that is, the seating surface gl2 during housing, in the housed state (folded state)! Therefore, the armrest function of the armrest portion g3 can be maintained even in the storage state (folded state).
- the armrest height can be adjusted lower than the back surface height in the accommodated state (folded state) in the unfolded state, so the thickness t (see FIG. 26) of the leg rest is relatively large. Even in this case, it is possible to prevent the armrest height from becoming too high in the deployed state, and to set the height appropriately.
- the height of the armrest part g3 is set with reference to the seating surface gl2 during storage. Therefore, there is a problem that the height of the armrest g3 becomes too high. This problem becomes more apparent when the leg placement part g5 has a massage mechanism. This is because, when the leg placement part g5 has a massage mechanism, the thickness t of the leg placement part tends to increase as described above.
- the chair type massage machine gl the height of the armrest g3 can be adjusted to be lower than the height of the seating surface gl2 when housed in the expanded state, so that the height of the armrest g3 can be adjusted appropriately even in the expanded state.
- the armrest height in the deployed state tends to be higher than necessary, but the armrest is higher than the height of the seating surface gl2 in the deployed state.
- the height of the armrest can be adjusted appropriately by adjusting the height of the part g3 low.
- the thickness of the leg mounting portion (accommodating state) In general, the maximum thickness in the vertical direction) is about 150mm-250mm, which is relatively thick. Therefore, the length of the movable range in the height direction of the armrest g3 is also 150 m corresponding to the thickness t. It is preferable to set it to m or more, more preferably 250 mm or more. In this way, even if the thickness t of the leg resting part is relatively thick, the armrest height can be set to an appropriate height even in the housing state (folded state) and the unfolded state! It is because it becomes easy to adjust.
