a cylindrical part (172) which extends in the axial direction of the wire from the case in such a manner as to surround the wiring hole; a seal member (167) which is housed in a compressed state in the cylindrical part, and surrounds the wire; and a cap (160) which is attached to the case in an attachable/detachable manner, has a hole (168) through which the wire passes, and prevents the seal member from moving. ## Claims ### Claim 1 A waterproof structure for an electronic device that acquires location information, which has been acquired by a receiving antenna provide on a vehicle, from the receiving antenna via a wire, the water proof structure comprising: a case disposed in a location in the vehicle distant from the receiving antenna, housing a processing unit that processes the location information, and having a wiring hole through which the wire passes; a cylindrical part extending in an axial direction of the wire from the case in such a manner as to surround the wiring hole; a seal member housed in the cylindrical part and sealing between the cylindrical member and the wire; and a cap detachably mounted to the case, having a hole for the passage therethrough of the wire, covering the seal member, and fitted with the cylindrical part. ### Claim 2 (depends on 1) The waterproof structure for an electronic device as defined in claim 1, the case includes a case body accommodating therein the processing unit, and a lid removably mounted to the case body and having the wiring hole. ### Claim 3 (depends on 1) The waterproof structure for an electronic device as defined in claim 1, wherein the cap includes a cap body for closing an end face of the cylindrical part, an outer cylindrical portion extending from an edge of the cap body toward the case in such a manner as to surround the cylindrical part, and a locking portion formed on the outer cylindrical portion for locking the cap, the locking portion being formed integrally with a distal end of the outer cylindrical portion and having a hook part for engagement with a tool or fingers when the locking portion is to be deflected toward the wire, and wherein the case has a locking prong for anchoring the locking portion. ### Claim 4 The waterproof structure for an electronic device as defined in claimed 3, wherein the locking portion has a locking hole for allowing passage therethrough of the locking prong. ### Claim 5 (depends on 4) The waterproof structure for an electronic device as defined in claim 4, wherein the cap is in engagement with the seal member to regulate movement of the seal member in a removing direction. ### Claim 6 (depends on 5) The waterproof structure for an electronic device as defined in claim 5, wherein the processing unit is disposed below a seat, and the receiving antenna is disposed in a front part of the vehicle. ### Claim 7 (depends on 6) The waterproof structure for an electronic device as defined in claim 6, wherein the processing unit is disposed in a region below a tandem seat, and the receiving antenna is disposed below a fuel tank provided behind a head pipe. ### Claim 8 (depends on 7) The waterproof structure for an electronic device as defined in claim 7, wherein the processing unit is disposed in a position overlapped, in a rear view of the vehicle, with a rear grip extending leftwards and rightwards from the seat in a vehicle width direction. ### Claim 9 (depends on 1) The waterproof structure for an electronic device as defined in claim 1, wherein the electronic device is a vehicular antitheft device for preventing theft of the vehicle based on the location information.
