Title:
MAGNETIC TYPE ROTATION TRANSMITTING MECHANISM
Document Type and Number:
WIPO Patent Application WO/2018/061190
Kind Code:
A1
Abstract:
This magnetic type rotation transmitting mechanism (1) has: a rotating plate (2) consisting of a magnetic material; and a magnet (3) to which the rotational movement of the rotating plate (2) is transmitted through the magnetic coupling between the magnet (3) and the rotating plate (2). When the rotating plate (2) is rotated, a plurality of oblique edge portions (4(1), 4(2)) formed on the outer peripheral edge of the rotating plate (2) rotate while sequentially passing through a position (6) that faces the magnet. The oblique edge portions (4(1), 4(2)) move in the direction of the centerline (2a) of rotation of the rotating plate (2), the direction of the centerline (2a) being perpendicular to the center axis (3a) of the magnet (3). The magnet (3) is rotated about the center axis (3a) by magnetic force occurring between the magnet (3) and the oblique edge portions passing through the position (6) facing the magnet. The provided mechanism for extracting rotation is small-sized and compact.
