ABSTRACT:
The present invention provides a tire air-pressure sensor (30) in which water is hard to intrude into a communication passage (36) communicating with a sensor portion (18a) of an air-pressure sensor element (18) and in which water having intruded into the communication passage (36) is discharged out of a case (32). Two air holes (34), (34) are formed in a crest portion of the case (32) of the tire air-pressure sensor (30) arranged and fixed in a wheel (10) in a manner to be positionally shifted in a rotating direction of the wheel (10), and an opening of an air vent hole (16) is formed in a cap (38) which is put on the air-pressure sensor element (18) arranged in the case (32), at an intermediate position between the two air holes (34), (34) in the rotating direction. The two air holes (34), (34) and the opening of the air vent hole (16) are brought into communication by the communication passage (36) on a substantial plane normal to the radial direction of the wheel (10), between the crest portion of the case (32) and the cap (38). Walls (40) are interposed between the air holes (34), (34) and the opening of the air vent hole (16) so as to bring the communication passage (36) into a meandering state.
