Claim:
A waterproof cable guide device for a railway vehicle, which is mounted to a cable guide of railcars which is provided with an introduction port through which a plurality of electric cables are guided to an electric device, the waterproof cable guide device comprising: an elastic member of a substantially rectangular prism shape, which has a plurality of through-holes into which the plurality of electric cables are inserted, respectively, the plurality of through-holes penetrating the elastic member in a forward and backward direction, the elastic member being divided in positions of the through-holes or having slits extending from an outer peripheral surface of the elastic member to the through-holes, respectively; a plurality of divided press casings into which a casing is divided in a vertical direction and in a lateral direction, the plurality of divided press casings surrounding a front surface, right and left side surfaces and upper and lower surfaces of the elastic member so as not to cover the through-holes; a first fastener member which tightens the plurality of divided press casings toward the cable guide to compress the elastic member toward the cable guide in a state where the electric cables are inserted into the through-holes, respectively; a second fastener member which tightens the plurality of divided press casings closer to each other in the vertical direction to compress the elastic member in the vertical direction, in a state where the electric cables are inserted into the through-holes, respectively; and a third fastener member which tightens the plurality of divided press casings closer to each other in the lateral direction to compress the elastic member in the lateral direction, in a state where the electric cables are inserted into the through-holes, respectively.
