Claims

[Scope of utility model registration request]

(1) A first having a cylindrical first connecting portion made of a magnetic material.
a second connecting body having a second connecting part made of a magnetic material facing the radially inner circumferential surface of the first connecting part with an annular gap therebetween, and having an annular groove opened in the outer peripheral part; magnetic particles sealed in the gap; a bobbin that is attached to the annular groove and has a flange in the opening direction of the annular groove; and a bobbin that is wound around the bobbin and magnetizes the magnetic particles to form the first connection main body. An electromagnetic coil for controlling the connection state with the second connecting body, and a resin made of a non-magnetic material attached to the annular groove so as to cover the outer periphery of the electromagnetic coil to magnetically block the opening of the annular groove. A magnetic particle type electromagnetic coupling device comprising a metal non-magnetic material attached to the annular groove so as to cover the outer periphery of the resin material.

(2) The magnetic particle type electromagnetic coupling device according to claim 1, wherein the annular groove has a shape that becomes narrower toward the outer periphery.

(3) The magnetic particle type electromagnetic coupling device according to claim 1 or 2, wherein the resin material and the metallic nonmagnetic material are bonded together.
