1. A lens driving device, comprising:
a lens support configured to support a lens;
a first moving, member plate and a second moving member plate that surround around a periphery of the lens support, wherein
the first moving member plate is supported so as to be freely movable relative to the second moving member plate by a first support mechanism that includes a first support protrusion and a first guide recess into which the first support protrusion is fitted,
the lens support is supported so as to be freely movable relative to the first moving member plate by a second support mechanism that includes a second support protrusion and a second guide recess into which the second support protrusion is fitted,
no guide recesses are formed on the first moving member plate while both the first support protrusion of the first support mechanism and the second support protrusion of the second support mechanism are formed on the first moving member plate so that the first support protrusion protrudes horn the first moving member plate towards one side of an optical axis direction of the lens and that the second support protrusion protrudes from the first moving member plate towards another side of the optical axis direction,
the first guide recess of the first support mechanism is formed on the second moving member plate so as to be recessed toward the one side of the optical axis direction, and the first guide recess has two side surfaces expanding along the optical axis direction so as to oppose to each other, and a bottom surface that connects the two side surfaces,
the second guide recess of the second support mechanism is formed on the lens support so as to be recessed toward another side of the optical axis direction, and the second guide recess has two side surfaces expanding along the optical axis direction so as to oppose to each other, and an upper surface that connects the two side surfaces.
