ABSTRACT:
An on-vehicle adaptor for a portable telephone which mounts a portable telephone so that the portable telephone is never disengaged unless a force larger than a certain level is applied thereto. The adaptor includes a case having a recess for receiving a swelled bottom of a large-capacity battery pack mounted to the portable telephone. The case has a pair of guides for guiding both sides of the portable telephone, a first projection adapted for engagement with a retaining slot formed in the portable telephone, and a second projection adapted for engagement with a retaining slot formed in the battery pack. The adaptor also includes a pair of ratchets adapted to enter and leave openings formed in the guides of the case, the ratchets each having a tapered portion whose thickness in the vertical direction is smaller at a front end thereof. Urging means are provided for urging the paired ratchets toward each other. The portable telephone is attached to the adaptor by engagement of the first and second projections with the associated retaining slots. Also disclosed is a portable telephone charger of a structure similar to that of the on-vehicle adaptor.
