Abstract
A lens module is fixed on a board body which is provided thereon with an imaging chip. The lens module comprises a seat body in which at least one lens is fixed for passage of rays of light from the outside of the seat body so as to form an image on the chip. An expandable tube is sandwiched between the seat body and the board body and is provided with a serpentine segment. A closed passage is formed between the lens and the chip. The expandable tube is provided thereon with a fixation member for limiting deformation of the serpentine segment of the expandable tube.
