DRIVE DEVICE |
| 摘要 |
A drive device includes: a base member having, on a surface, an operation base part made up of one or more operation recesses; and a movable member disposed to be opposed to the base member and having, on the opposing surface, operation projections to be inserted into the operation recesses. A shape memory alloy member is interposed between the base member and the movable member, and the movable member is moved so as to be separated away from the base member in response to the contraction of the shape memory alloy member when energized. The drive device includes a spring which is supported by the base member and bias the movable member so as to be separated away from the base member. |

1. A drive device comprising:
a base member having, on a surface, an operation base part made up of one or more operation recesses; and a movable member disposed to be opposed to the base member and having, on an opposing surface, operation projections to be inserted into the operation recesses, the drive device configured such that a linear or belt-shaped shape memory alloy member which is contracted by heat generated when energized is interposed between the base member and the movable member, and the movable member is moved so as to be separated away from the base member in response to the contraction of the shape memory alloy member when energized, the drive device comprising a spring which is supported by the base member and which biases the movable member so as to be separated away from the base member. |
