DRIVE MECHANISM, ACTUATOR, AND VALVE

摘要

A driving mechanism (100) includes a first rotor (10) that rotates around a first shaft L1 and a second rotor (20) that rotates around a second shaft L2 that is provided in parallel with the first shaft L1. The first rotor (10) includes a guide (13) that extends in a circular arc around the first shaft L1 and a drive pin (14) that is provided outside the guide (13) relative to the first shaft L1. The second rotor (20) includes a first member (40) with a plurality of leads (41) that extend in the radial direction from the second shaft L2 and a second member (50) that is provided between the first rotor (10) and the first member (40), that moves together with the first member (40), and that includes a plurality of first surfaces (51) with substantially the same curvature as a circular arc-shaped outer surface (13b) of the guide (13).
