<p><P>PROBLEM TO BE SOLVED: To provide an on-vehicle communication terminal device capable of exerting high waterproof performance. <P>SOLUTION: In this on-vehicle communication terminal device 1 loaded in a vehicle, performing information communication about passage information of the vehicle with a stationary communication terminal, a cover part 6 has a packing 9 liquid-tightly contacting with an upper case 3 such that a distance between the outside of a side face of the upper case 3 and the inside of a side face of the cover part 6 becomes 1 mm or above when the cover part 6 is closed to the upper case 3. A distance L2 from a gap part H between the cover part 6 and the upper case 3 to the packing 9 is set to correspond to an approximate half of an overall height L3 of the on-vehicle communication terminal device 1 to lengthen an infiltration path W2 of water. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
