PROBLEM TO BE SOLVED: To provide an actuator 1 which moves a mobile body 3 attached to a rotation axis 2 depending on rotation of the rotation axis 2, and increases a moving range of the mobile body 3 while suppressing resonance of the rotation axis 2. ! SOLUTION: A movable range Rb of a support member 6 on one side of a mobile body 3 and a movable range Rd of a support member 6 on the other side of the mobile body 3 overlap each other in an X direction at least in a part. In other words, the movable ranges Rb, Rd of the support members 6 ensure a wide range to a degree such that the movable ranges Rb, Rd overlap each other thereby to meet an increase in moving range of the mobile body 3. As a result, the moving range of the mobile body 3 can be increased while suppressing resonance of a rotation axis 2. ! COPYRIGHT: (C)2015,JPO&INPIT |
