PURPOSE: An apparatus for controlling the focus of camera lens module is provided to be used by being applied regardless of the type of lens module, thereby precisely and finely controlling the focus of lens module. CONSTITUTION: An apparatus for controlling the focus of camera lens module (F) includes a rotating body, a guide member, a connection pin, a control member, a fixing plate, a coupling plate, and a waterproof pad. The guide member guides the rotation of rotating body. The connection pin has one end that holds the rotating body and the other end that is coupled to the lens module, thereby connecting the rotating body and the lens module. The controlling member rotates the rotating body and rotates the lens module that is connected by the connection pin, thereby controlling the focus of lens module. The fixing plate fixes the guide member, and contacts and supports the rotating body, thereby guiding the rotation of rotating body together with the guide member. The coupling plate is coupled to the fixing plate by a head of control member by exposing. The waterproof pad is interposed between the fixing plate and the coupling plate, and surrounds the outer circumferential edge of control member.
