[0025]

[0026] exist figure 1 Among them, the movable device 1 has a base 2 and a movable mechanism 3 . The abutment 2 is fixed to an appropriate base part according to the application. The base 2 can be fixed to a vehicle body, for example. The movable mechanism 3 can move mechanically relative to the base 2 . The movable mechanism 3 is capable of rotational movement about a rotational axis AXR extending along the height direction HD. The movable mechanism 3 can reciprocate within a predetermined angular range around the rotation axis AXR. The movable mechanism 3 has a driven body 31 . The action of the movable mechanism 3 is also referred to as swinging. In addition, the moving direction of the movable mechanism 3 is not limited to rotation. The movement direction of the movable mechanism 3 is applicable to various operations such as parallel movement along the height direction HD, parallel movement along the width direction WD, and rotational movement around the de...

no. 2 approach

[0065] This embodiment is a modified example based on the previous embodiment. In the above-described embodiment, the orientation direction ORP and the longitudinal direction LD44 define the tilt angle AC. Instead here, the orientation direction ORP and the length direction LD 244 may extend in parallel.

[0066] exist Figure 5 Among them, the longitudinal direction LD244 of the polymer member 244 , that is, the circumferential direction CD coincides with the orientation direction ORP. Therefore, the orientation direction ORP is parallel to the length direction LD244. However, the orientation direction ORP and the length direction LD244 may also have a slight tilt angle. In addition, the orientation direction ORP and the longitudinal direction LD244 may be microscopically inclined inside the polymer member 244 . In addition, when the width of the base material BMT matches the width of the polymer member 244 , the polymer member 244 may be provided only by cutting the base...

no. 3 approach

[0068] This embodiment is a modified example of the previous embodiment as a basic form. In the above-described embodiments, the polymer member 44 has gaps between layers. Instead, the polymer component 44 can have elastic components 361 arranged between layers.

[0069] Such as Figure 6 As shown, the actuator element 43 has a scroll-shaped polymer member 44 and an elastic member 361 filling the radially inner side of the polymer member 44 . The elastic member 361 is bonded to the polymer member 44 . The elastic member 361 allows deformation of the polymer member 244 by its own elasticity. The elastic member 361 may be provided by an elastic member such as rubber or elastic body. According to this embodiment, the shape of the actuator element 43 can be stabilized.

Abstract

A movable device (1) is provided with an actuator element (43). The actuator element has a resin polymer member (44) that is disposed so as to extend in a peripheral direction, and that expands and contracts in the peripheral direction depending on a change in the energy state. The movable device is provided with a fixed part and a movable part. The fixed part is connected to a fixed end (43a) ofthe actuator element, and fixes the actuator element. The movable part is connected to a movable end (43b), of the actuator element, located apart from the fixed end in the peripheral direction. The polymer member is disposed so as to extend in the peripheral direction, and therefore the polymer member can provide a sufficient length in the peripheral direction. Thus, the movable end of the actuator element can provide a larger displacement amount with respect to the fixed end.
