<P>PROBLEM TO BE SOLVED: To provide an in-vehicle electronic device which never hinders removing operation of a circuit board with being mounted on a glass surface of a vehicle window portion. <P>SOLUTION: The in-vehicle electronic device 10 includes a circuit board 1 provided with a preamplifier circuit and the like, and a holding case 4 which stores the circuit board 1. The holding case 4 is configured by combining a lower case 6 which is fixed to a glass surface 20 on which an antenna radiation conductor is arranged, and an upper case 7 which is detachably mounted on the lower case 6 so as to cover it, so that a connection terminal 5 held in the lower case 6 is brought into press-contact with an electrode 9 of the circuit board 1 held in the upper case 7. When the upper case 7 is removed from the lower case 6, an elastic piece 7a is bent by pushing a tip of a protruded portion 7b to a base end side, or a snap claw 7c is separated from a locking hole 6c of a tongue piece 6b by inserting a tool such as a driver in between the tongue piece 6b and the elastic piece 7b. <P>COPYRIGHT: (C)2013,JPO&INPIT |
