A tire wear measuring device that detects wear of a tire based on a magnetic field from a magnetic object embedded in the tire includes magnetic sensors and a battery. The battery is capable of transmitting the magnetic field from the magnetic object, and has an outer edge from which the magnetic field from the magnetic object is emitted as an emission magnetic field. Each of the magnetic sensors is disposed in a position where the emission magnetic field is detectable by the sensor.

Tire wear measuring device and power generating device

A first main body portion and a second main body portion of an electronic package are mounted on a mount portion of a support body, first metal projections are caused to enter first receiving recesses, and second metal projections are caused to enter second receiving recesses. When a clip member is mounted in the a first direction, the first metal projections are pressed by first pressing portions of the clip member, the second metal projections are pressed by second pressing portions of the clip member, and an elastic piece is pressed against a rear side of the support body. Thus, the electronic package is secured.
