Claim 2:
3. A bracket that is pressed against and fixed to an outer peripheral surface of a rim of a tire wheel by a belt wound around the outer peripheral surface of the rim, and detachably holds an electric circuit unit, the bracket comprising:
a pair of rim contact portions that are provided at both ends in a circumferential direction of the rim in a rim facing surface facing the outer peripheral surface of the rim, and come into contact with the outer peripheral surface of the rim in such a way as to cause a portion between the both ends to be spaced apart from the outer peripheral surface of the rim;
a base portion that extends in the circumferential direction of the rim and has the rim facing surface inside the base portion; and
a pair of slits that pass through both ends of the base portion or positions close to the both ends to allow the belt to pass through, wherein:
a portion between the pair of slits in the rim facing surface faces the outer peripheral surface of the rim interposing the belt interposed in between,
the electric circuit unit includes a pair of engagement protrusions that protrude in pairs toward the outer peripheral surface of the rim, and foot portions having tip portions enlarged with respect to base end portions in a direction perpendicular to both a direction in which the pair of engagement protrusions protrude and a direction in which the pair of engagement protrusions face each other,
the bracket comprises:
a pair of pedestal protrusions that protrude from the both ends of the base portion to a side opposite to the rim facing surface and have, at tip portions, upper surface walls perpendicular to a direction of the protrusion;
a pair of engagement holes that pass through the upper surface walls of the pair of pedestal protrusions;
wide portions that are provided in the pair of engagement holes and just suitable for the foot portions of the pair of engagement protrusions to pass through;
narrow portions that are provided in the pair of engagement holes, located on one side of the wide portions in a direction in which the pair of pedestal protrusions are aligned, and suitable for the base end portions of the pair of engagement protrusions to pass through; and
a retainer that is inserted into one of the wide portions, and

the pair of engagement protrusions are inserted into the wide portions of the pair of engagement holes, the electric circuit unit is moved in the direction in which the pair of pedestal protrusions are aligned, the base end portions of the pair of engagement protrusions are engaged with the narrow portions of the pair of engagement holes, and then the retainer is inserted into the wide portion of any of the pair of engagement holes.
