Abstract:
To rotate a shaft to move a movable body smoothly in a curved manner.SOLUTION: In a driving device 1, at least a part of a rail 100 curves so that an opening groove 110 curves when the rail 100 is viewed from a lateral side Z orthogonal to an axial direction X. A shaft 200 may rotate in a circumferential direction. The shaft 200 has flexibility. The shaft 200 has an engaging part 210 formed in a spiral shape on a peripheral surface. A movable body 300 may be moved along the axial direction X by the shaft 200 rotating. An engaged part 320 is engaged with an engaging part 210 of the shaft 200. The engaged part 320 may move in a first direction D1, a direction along the engaging part 210, when viewed from the lateral side Z. A position of the engaged part 320 is fixed relative to the case part 310 in a second direction D2 orthogonal to the first direction D1 when viewed from the lateral side Z.SELECTED DRAWING: Figure 8
