Title:
ELECTROMAGNETIC CLUTCH
Document Type and Number:
WIPO Patent Application WO/2017/199636
Kind Code:
A1
Abstract:
An electromagnetic clutch (8) is provided with a driving-side rotating member (10), a driven-side rotating member (20), and an electromagnetic coil (30). The driven-side rotating member is provided with an armature (21), an inner hub (23), a holding member (25), and a contact section (24). The holding member allows a thread fastening structure (26) to become loose when torque transmitted from the driving-side rotating member through the inner hub to a rotating shaft (2a) is greater than or equal to a predetermined value. The contact section is disposed at a distance from the armature when the thread fastening structure is not loosened, and when the inner hub is moved relative to the rotating shaft by the loosening of the thread fastening structure, the contact section moves with the inner hub relative to the rotating shaft to come into contact with the armature.
