ABSTRACT:
A waterdrop-proof camera includes lens frames which are moved backward and forward relative to an optical axis during zooming or focusing; a camera main body in which the lens frames are slidably held in a liquid-sealed state; vent holes, provided in positions where they will not be covered by the hand of a user, on either the wall surface of the camera main body or that of the lena frames, through which vent holes the inside of the camera is communicated with the outside thereof; and a sheet-like member, having sufficient water repellency and air permeability, arranged on the camera body containing the inner side of the vent holes so as to seal them. A sealing member formed from a elastic member is fixed to either one of first and second lens frames which move relative to each other, by which sealing member one of the lens frames is radially pressed against the other, so that a section between the two lens frames is waterproofed. In addition, a device is disposed for increasing the amount of pressure at a specific focal distance or in a state in which the lens frames are housed.
