First Claim
Patent Images
1. A case for a transmitter, wherein the transmitter is adapted for attachment to a wheel inside a tire and for transmitting information concerning tire pressure, the case comprising:
- a first plate;
a second plate that is generally parallel to the first plate; and
a plurality of ribs, wherein each rib is located at the periphery of the case and is located between the first plate and the second plate, wherein each ribs has an inclined surface, wherein the inclined surface of at least one of the ribs has a smaller angle of inclination with respect to the second plate than that of the other ribs, and wherein the inclined surface of the at least one rib is located to guide the tire over the case when the tire is being removed.

Abstract
A transmitter casing has an upper plate and a lower plate, which face each other. A rib is located to incline with respect to the lower plate between the upper plate and the lower plate. The rib prevents the tire from interfering to the casing if the tire is detached from the wheel. This enables smooth detaching of a tire from a wheel without interference with the transmitter, and to strengthen the casing of the transmitter.
