20 Claims

1. A lens driving apparatus, comprising:

a base;

a housing disposed on the base;

a bobbin disposed in the housing;

a first coil disposed on an outer circumferential surface of the bobbin;

first magnets disposed on the housing and opposite the first coil;

a circuit board comprising a second coil disposed so as to face the first magnets;

an upper elastic member coupled to both an upper surface of the bobbin and the housing;

a first sensor detecting displacement of the bobbin in a first direction parallel to an optical axis direction; and

a plurality of support members electrically connecting the upper elastic member to the circuit board,

wherein the bobbin comprises a protrusion more protruding from the outer circumferential surface of the bobbin than the coil,

wherein the protrusion of the bobbin comprises a first protrusion, and a second protrusion adjacent to the first protrusion,

wherein the first protrusion and the second protrusion protrude in a second direction and a third direction, which are perpendicular to each other and perpendicular to the first direction,

wherein the first protrusion and the second protrusion are disposed alternately, forming a first space and a second space therebetween,

wherein the first space is formed between the first protrusion and the second protrusion which are protruding in a direction perpendicular to each other,

wherein the second space is formed between the first protrusion and the second protrusion which are protruding in a direction parallel to each other,

wherein the housing comprises a first portion including a third protrusion protruding toward the bobbin at a position corresponding to the first space,

wherein the first sensor is disposed on the bobbin and overlapped with the second space, and

wherein a surface of the third protrusion has the same shape as a side surface of the bobbin at a position corresponding to the first space.
