# Machine component, power transmission device, and robot

## Abstract

A machine component includes a base portion and strain gauges. The base portion extends in a direction intersecting a central axis. The strain gauges are provided on the base portion and arrayed in a circumferential direction about the central axis. Gap regions are provided between adjacent strain gauges in the circumferential direction. The gap regions include gap regions arranged at angular intervals of approximately 90° about the central axis.
