FIELD: machine building.
SUBSTANCE: invention relates to automotive industry. Transmitting device used in said system for controlling tyre information includes: a sensor which detects state of gas filling tyre cavity as tyre information; a transmitter transmitting detected tyre information; and a wall covering sensor and transmitter. Wall forms an internal space divided from tyre cavity and a communicating hole penetrating wall and providing communication between internal space and tyre cavity. Inside opening part of communicating hole in a surface of a housing facing internal space is formed with a greater opening area than an outside opening part of communicating hole in a surface of housing facing tyre cavity. In a surface of wall facing communicating hole, a recessed part which is recessed toward surface of housing including outside opening part is formed.
EFFECT: technical result is improved control of tyre information.
