Abstract
A movable device includes: a movable portion; a driving section configured to generate a driving force to move the movable portion; a movement mechanical section; and at least one convex portion. The movement mechanical section includes: a contact portion contacting the movable portion, the contact portion movable in a movement direction by the driving force of the driving section; and multiple concave-convex portions movable with the contact portion in the movement direction. At least one convex portion engaging with corresponding one of the multiple concave-convex portions, said at least one convex portion being static relative to the movement mechanical section in the movement direction.

A movable device comprising:
- a movable portion, and a torsion bar that supports the movable portion;
- a driving section configured to generate a driving force to move the movable portion;
- a movement mechanical section including:
- a contact portion contacting the movable portion, the contact portion movable in a movement direction by the driving force of the driving section, wherein the contact portion moves in response to a drive of the driving section and tilts the movable portion about a rotation axis;
- and
- multiple concave-convex portions movable with the contact portion in the movement direction,
- at least one convex portion engaging with corresponding one of the multiple concave-convex portions, said at least one convex portion being static relative to the movement mechanical section in the movement direction,
- wherein a torsional stiffness of the torsion bar about the rotation axis is smaller than a stiffness of the at least one convex portion in a direction in which the at least one convex portion faces the multiple concave-convex portions.
