An actuatorincludes a housing, an output shaftprotruding from the inside of the housingto the outside, a motorprovided in the housing, and a reduction mechanismthat connects the motorwith the output shaft. The reduction mechanismincludes a worm gear, in which a wormprovided at a front end of a drive shaftprotruding from a main bodyof the motorand a worm wheelrotating integrally with the output shaftare engaged. A spindlefor increasing an inertia is provided between the wormof the drive shaftand the motor body

Actuator and exhaust valve driving device

An actuatorincludes a housing, an output shaftprojecting from the inside of the housingto the outside, a motorprovided in the housing, a reduction mechanismwhich connects the motorto the output shaft, a magnetprovided for rotation integrally with the output shaftinside the housing, a Hall effect ICdisposed to face the magnetoutside the rotation locus of the magnet, and a circumferential walldisposed to stand from the inner wall of the housingand interposed between the magnetand the Hall effect IC

In an Oldham coupling, a first protruding part, protruding in a coaxial direction parallel to and extending in a first direction, is provided in one of first and second members, and the other of the first and second members includes a first notch part fitted to the first protruding part and slidable in the first direction along the first protruding part. A second notch part, extending in a second direction perpendicular to the first direction, is formed in one of second and third members, and the other of the second and third members includes a second protruding part fitted to the second notch part and slidable in the second direction along the second notch part. At least one of the first, second, and the third members has a heat dissipating structure including mutually separated concentric hollow cylinders of different diameters, connected by a bridge part.
