<p>PURPOSE:To reduce the radial length of a solenoid coupling by making the cylindrical part of an internal member forming a part of a yoke, out of sintered alloy having magnetical characteristics and having the cylindrical part which supports a rotor. CONSTITUTION:The cylindrical part of an internal member 21a forming a part of a yoke 21 is made of sintered alloy having magnetical characteristics and the cylindrical part supports a rotor 23. Since no bearing may be needed in this way, a coupling can be radially shortened by a length corresponding to the thickness of the bearing.</p> |
