<p><P>PROBLEM TO BE SOLVED: To provide an electromagnetic clutch capable of easily and securely preventing lubricating oil leaking from an oil-retaining bearing from flowing to the friction surface of an input shaft side friction plate and the friction surface side of an output shaft side friction plate at a low cost. <P>SOLUTION: The electromagnetic clutch 10 is provided with a clutch body 11, a coil 12 wound around the clutch body, an input shaft 13 rotatably supported in the clutch body via the oil-retaining bearing 15 while forming an outside spline at a tip outer circumference and providing an input shaft side friction plate 14 at a base end 13b, an output shaft 16 having an output shaft side friction plate 18 with a friction surface 18b attracted and departed by the friction surface 14c of the input shaft side friction plate at a base 16a, forming an output gear 16c linked with a load in the base end and rotatably supported to the input shaft via an oil-retaining bearing 19 and a leaf spring 20 for energizing the output shaft side friction plate in a direction for separating from the input shaft side friction plate when electricity is not applied to the coil. In this case, a porous member 17 in an annular plate shape is provided between the base 16a of the output shaft 16 and the output shaft side friction plate 18. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
