As shown in FIG. 2, the mounting portion 11 has two sides.
It is configured by laminating _two sheet materials 11 ₁ and 11 ₂ . That is, the sheet material 11 ₁ is positioned on the front side (the back of the hand) side of the left hand 100, the sheet material 11 ₂ is positioned on the back side of the left hand 100 (palm). The front sheet material 11 ₁ is made of a surface material 11A whose core is a heat insulating material such as polyurethane.
And a smart material (intelligent material) 11B as a bending means wrapped in the surface material 11A.

The smart material 11B is used as an insulating material, for example, a carbon / epoxy base material (fiber-reinforced composite material).
In 11C, Ti as a shape memory alloy actuator
-Ni fiber 11D is embedded. Ti
-The Ni fiber 11D is made of an elongated rod-shaped Ti-Ni alloy. A large number of Ti-Ni fibers 11D are arranged in the base material 11C along the fingers 100a to 100e. The Ti-Ni fiber 11D generates Joule heat due to electric resistance when energized. This heat heats the Ti-Ni fiber 11D itself,
Since the surface material 11 </ b> A uses a heat insulating material as a core material, heat is prevented from being transmitted to the hand 100.

The Ti-Ni fiber 11D is
The deformation is repeated between an extended state (linear state) of 0a to 100e and a bent state, and the extended state or the bent state is stored under a predetermined temperature. Then, Joule heat is generated in the Ti-Ni fiber 11D by energization, and when the Ti-Ni fiber 11D becomes higher than a predetermined temperature, the Ti-Ni fiber 11D causes a bending motion from the original shape, and by stopping the energization, Ti-Ni
When the temperature of the fiber 11D becomes lower than the predetermined temperature, the fiber 11D returns to the original shape again. Ti-
Although not shown, both ends of the Ni fiber 11D are provided with current-carrying wiring. The wiring is connected to the connection line 14. Further, each Ti-Ni fiber 11D is electrically connected in series or parallel by a connection line 14. Ti-Ni fiber 1
