1. A lens driving device comprisinga shake-correcting driving part, the shake-correcting driving part including:

  • a shake-correcting magnet part disposed at a periphery of a lens part;

    a shake-correcting coil part separated from the shake-correcting magnet part; and

    a supporting part configured to support a shake correction movable part including the shake-correcting magnet part such that the shake correction movable part is separated from a shake correction fixing part including the shake-correcting coil part in a light axis direction, the shake-correcting driving part being configured to sway the shake correction movable part with respect to the shake correction fixing part in a plane orthogonal to the light axis direction by utilizing a driving force of a voice coil motor composed of the shake-correcting coil part and the shake-correcting magnet part to perform a shake correction, wherein;

    the supporting part includes;

    an upper frame member disposed opposite to the shake correction fixing part in the light axis direction,two first side supporting members disposed opposite to each other in a first direction orthogonal to the light axis direction, each of the first side supporting members having a plate shape and being configured to couple the upper frame member and the shake correction fixing part, andtwo second side supporting members disposed opposite to each other in a second direction orthogonal to the light axis direction and the first direction, each of the second side supporting members having a plate shape and being configured to couple the upper frame member and the shake correction movable part,the first side supporting members and the second side supporting members are formed with an elastomer material,each of the first side supporting members includes first and second Y-hinge parts that are thinner than a portion around the first and the second Y-hinge parts and that extend in the second direction, whereineach of the first side supporting members is bent along with movement of the shake correction movable part in the first direction such that bending directions of the first Y-hinge parts are identical to each other and bending directions of the second Y-hinge parts are identical to each other while the bending directions of the first Y-hinge parts and the bending directions of the second Y-hinge parts are opposite to each other,each of the second side supporting members includes first and second X-hinge parts that are thinner than a portion around the first and the second X-hinge parts and that extend in the first direction, whereineach of the second side supporting members is bent along with movement of the shake correction movable part in the second direction such that bending directions of the first X-hinge parts are identical to each other and bending directions of the second X-hinge parts are identical to each other while the bending directions of the first X-hinge parts and the bending directions of the second X-hinge parts are opposite to each other.
