Abstract: An automatic hair washing device includes a washing part including a cover member having a head holding space, a plurality of contacts each of which is formed of a rod-shaped member, and energization means for energizing the contacts to move toward the head holding space, wherein the energization means includes an accommodation space where a fluid is accommodated and a fluid pressure adjustment part to adjust a pressure of the fluid accommodated in the accommodation space at a predetermined level, and the fluid pressure adjustment part is configured to adjust the pressure of the fluid accommodated in the accommodation space at a pressure to energize the contacts toward the head holding space such that the contacts are in contact with the human head apply approximately constant forces to the human head even when the contacts are moved by the human head.

Abstract: [Object] Provided is an automatic hair washing device configured to achieve a hair washing operation like hair washing by human hand. [Solution] An automatic hair washing device includes a washing part 10. The washing part 10 includes: a cover member 11 having a head holding space 11h where a human head is placed; a plurality of contacts 12 each formed of a rod-shaped member and each disposed on an inner face 11a of the cover member 11 in an axially movable manner; and energization means 20 for energizing the contacts 12 toward the head holding space 11h. The washing part 10 is disposed such that the cover member 11 is movable along the human head. The energization means 20 is configured to energize the contacts 12 toward the head holding space 11h such that the contacts 12 being in contact with the human head apply approximately constant forces to the human head even when the contacts 12 are moved.
