Abstract
Conventional pressure sensor units require time-consuming work including bonding and welding in assembly work and affixing a pressure sensor to a holder, and therefore a pressure sensor unit in which a pressure sensor can be easily affixed to a holder is needed. Disclosed is a pressure sensor unit wherein a holder comprises a first holder member and a second holder member, and by fitting a fitting groove of the first holder member and a fitting claw of the second holder member with each other while housing a pressure sensor in housing holes provided in the two holder members, the two holder members are affixed, and the pressure sensor is affixed to the holder.

14. A pressure sensor unit comprising:
-
a pressure sensor for detecting air pressure and for outputting an electrical signal corresponding to a detected air pressure; an electronic substrate for electrically processing the electrical signal output from the pressure sensor; and a holder for holding the pressure sensor and the electronic substrate; wherein the holder comprises; a first holder member comprising a first housing hole for housing a portion of the pressure sensor and for connecting to an air circuit where the pressure is to be detected, the first holder member on which a first flange is formed in an inner periphery of the first housing hole; and a second holder member comprising a second housing hole for housing the part of the pressure sensor not housed in the first housing hole, provided facing the first housing hole, and the second holder member on which a second flange is formed in an inner periphery of the second housing hole; wherein the pressure sensor is affixed between the first housing hole and the second housing hole by being sandwiched between the first flange and the second flange. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25)

26. A brake device comprising:
-
an air compressor for compressing air; a tank for storing air compressed by the air compressor; and
,a pressure sensor unit for detecting the air pressure in the tank; wherein the pressure sensor unit comprises a pressure sensor for detecting air pressure from the brake mechanism and for outputting an electrical signal corresponding to the detected air pressure; an electronic substrate for electrically processing the detected electrical signal from the pressure sensor; and a holder for holding the pressure sensor and the electronic substrate; wherein the holder comprises; a first holder member comprising a first housing hole for housing a portion of the pressure sensor and for connecting to an air circuit where the pressure is to be detected, the first holder member on which a first flange is formed in an inner periphery of the first housing hole; and a second holder member comprising a second housing hole for housing the part of the pressure sensor not housed in the first housing hole, provided facing the first housing hole, and the second holder member on which a second flange is formed in an inner periphery of the second housing hole; wherein the pressure sensor is affixed between the first housing hole and the second housing hole by being sandwiched between the first flange and the second flange. - View Dependent Claims (27, 28)

29. A pressure sensor unit comprising:
-
a pressure sensor for detecting air pressure; an electronic substrate for electrically processing signals from the pressure sensor; and a holder for holding the pressure sensor and the electronic substrate;
wherein the holder comprises;a first holder member comprising a first housing hole for housing a portion of the pressure sensor; and a second holder member comprising a second housing hole for housing the part of the pressure sensor not housed in the first housing hole, and provided facing the first housing hole;
whereinthe pressure sensor is housed in the first housing hole and the second housing hole such that a direction parallel to an air pressure application direction of the pressure sensor matches the direction of depth of the first housing hole and the second housing hole; one of the first holder member and the second holder member comprises a first fitting groove; the other one of the first holder member and the second holder member comprises a first fitting claw provided at a position corresponding to the first fitting groove; the first holder member and the second holder member are affixed together by fitting the first fitting claw into the first fitting groove and the pressure sensor is affixed to the holder; and in a state in which the first fitting claw is fitted into the first fitting groove, the length from the bottom surface of the first housing hole to the bottom surface of the second housing hole is equal to the total length of the pressure sensor in a direction parallel to the air pressure application direction.
