Abstract: The actuator includes a movable body, a support body with a case that accommodates the movable body and a coil holder, connecting bodies connected to the movable body and the support body, a magnetic drive circuit including a coil and magnets opposed to the coil in a Z direction and causing the movable body to vibrate in an X direction with respect to the support body, and a buffer material fixed to the case and opposed to the movable body in the X direction. When the magnetic drive circuit is driven with a first voltage, the movable body vibrates without colliding with the buffer material. When the magnetic drive circuit is driven with a second voltage, which is larger than the first voltage, the movable body collides with the case through the buffer material, whereby an impulsive force is generated.

Abstract: In an ice making device, a frame supporting an ice tray and a drive unit has a first wall at a side of an ice detection member. Supported on the first wall is a regulation member rotatable between a first rotation position not to regulate coming down of the ice detection member and a second rotation position to regulate coming down of the ice detection member. By moving the regulation member to the second rotation position, later ice making is stopped even if ice accumulating below is not much. The regulation member includes a regulator in a circular arc form and is supported rotatably around a shaft. The regulation member as a rotary member is less liable to unexpectedly move from either of the first rotation position and the second rotation position, so that movement of the regulation member to a position not intended is suppressed.

Abstract: The present invention provides a wide-angle lens capable of obtaining a suitable negative power even when a thickness of a first lens is increased in order to increase strength against impact. The wide-angle lens 100 has a front group 110, an aperture 80, and a rear group 120. Assuming that a central thickness in an optical axis direction of a first lens 10 is T1 (mm) and a focal length of the entire lens system is f0 (mm), the following conditional expression: 1.500?T1/f0?2.000??Conditional expression (1) is satisfied. Therefore, it is possible to suppress the first lens 10 from being damaged by impact. In addition, it is possible to prevent the first lens 10 from becoming too thick to obtain suitable negative power.
