|発明の名称||SHAPE-MEMORY VARIABLE RIGIDITY MECHANISM MODULE AND SHAPE-MEMORY VARIABLE RIGIDITY SHEET|
PROBLEM TO BE SOLVED: To provide a shape-memory variable rigidity mechanism module and a shape-memory variable rigidity sheet, capable of being adapted to any curved surface, performing switching between states at a high speed, and suppressing energy consumption for maintaining rigidity as much as possible.
SOLUTION: A shape-memory variable rigidity mechanism module comprises a first lock member having a frictional surface, a second lock member having a frictional surface being in contact with the first frictional surface, a bistable elastic member having a first stable state and a second stable state, and an actuator for switching between the first stable state and the second stable state. The bistable elastic member is disposed at a position where the first lock member and the second lock member come in contact with each other with a maximum frictional force in the first stable state.
