1. An actuator, comprising:
- a holder;
a slider slidably held by the holder;
a wire locked at a first position on the slider, the wire causing the slider to slide by contracting in at least a line length direction when being energized, the wire having first and second ends, and the wire being locked on the slider at a fold in the wire;
first and second electrode units, the first end of the wire being bonded to the first electrode unit, the second end of the wire being bonded to the second electrode unit; and
an elastic plate having first and second end portions, the first end portion of the elastic plate being fixed to the slider at a second position different from the first position, the second end portion of the elastic plate being fixed to the holder at a position separated from the slider in a sliding direction of the slider,wherein, when the wire is energized, the slider slides in the sliding direction and the elastic plate elastically deforms in a direction perpendicular to the sliding direction due to a change in a distance between the first end portion of the elastic plate and the second end portion of the elastic plate from sliding of the slider.

Abstract
This actuator includes: a holder; a slider; a wire; and a pair of electrode units. The slider is slidably held by the holder. The wire is a member that is locked at the slider, the wire causing the slider to slide by contracting in at least a line length direction when being energized. One end of the wire is bonded to one of the electrode units, and the other end of the wire is bonded to the other of the electrode units.

10. An alarm apparatus, comprising:
-
an actuator including a holder, a slider slidably held by the holder, a wire locked at a first position on the slider, the wire causing the slider to slide by contracting in at least a line length direction when being energized, the wire having first and second ends and a fold between the first and second ends, and the wire being locked on the slider at the fold in the wire, first and second electrode units, the first end of the wire being bonded to the first electrode unit, the second end of the wire being bonded to the second electrode unit; and a strip-shaped member having first and second end portions, the first end portion of the strip-shaped member being fixed to the slider of the actuator at a second position different from the first position, the second end portion of the strip-shaped member being fixed to distal end portion of the holder, the distal end portion of the holder being separated from the slider in a sliding direction of the slider, wherein, when the wire is energized, the slider slides in the sliding direction and the strip-shaped member elastically deforms in a direction perpendicular to the sliding direction due to a change in a distance between the first end portion of the strip-shaped member and the second end portion of the strip-shaped member from sliding of the slider, and wherein elastic deformation of the strip-shaped member in the direction perpendicular to the sliding direction enables the strip-shaped member to provide an alarm notification to a user.
