An optical deflecting device including a supporting member, an oscillating member, and a driving member for driving the oscillating member, wherein the oscillating member includes a first movable element and a second movable element torsionally oscillating about a common torsion axis, a first torsion spring for coupling the first movable element and the supporting member with each other, and a second torsion spring for coupling the first and second movable elements with each other and having a torsion axis the same as the first torsion spring, and wherein the first movable element is formed with a void configured to avoid blocking of incident light being incident on the second movable element from a direction intersecting with the torsion axis.
