Claim 1:
2. 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;
a pressed portion that is provided between the pair of rim contact portions in the base portion and pressed by the belt toward the outer peripheral surface of the rim, causing the base portion to sag;
a pair of facing support portions that protrude from both ends of the base portion toward a side opposite to the rim facing surface and receive and support the electric circuit unit between the pair of facing support portions; and
a pair of slits that pass through base end portions of the pair of facing support portions to allow the belt to pass through, wherein:
the base portion sags toward the outer peripheral surface of the rim in such a way that the pair of facing support portions tilt toward each other;
the electric circuit unit includes a first engagement protrusion that protrudes toward a first facing support portion that is one of the pair of facing support portions, and a second engagement protrusion that protrudes toward a second facing support portion that is an other one of the pair of facing support portions, and
the bracket further comprises:
a first engagement hole that passes through the first facing support portion to allow the first engagement protrusion to be inserted from the second facing support portion side;
a second engagement hole that passes through the second facing support portion and has a protrusion receiving port that opens on a tip surface or side surface of the second facing support portion to allow the second engagement protrusion to be inserted from the protrusion receiving port; and
a retainer that is inserted into the second engagement hole into which the second engagement protrusion has been inserted, from a side opposite to the first facing support portion to restrict the second engagement protrusion from moving toward the protrusion receiving port.
