    • To reduce running cost while preventing production of noise.Provided are a pair of magnetic meshing rings (151) including magnetic meshing teeth (151b) arranged side by side on both an inner circumferential surface and an outer circumferential surface of a middle yoke member (15); a magnet member (152) situated between the pair of the magnetic meshing rings (151) such that the magnetic meshing teeth on one of the magnetic meshing rings (151) and magnetic meshing teeth on the other one of the magnetic meshing rings (151) have opposite magnetic poles; and a pair of meshing tooth rows (25) including a plurality of meshing teeth (25a) arranged side by side on an outer circumferential surface of an inner yoke member (21) and on an inner circumferential surface of an outer yoke member (22) and facing the magnetic meshing rings (151), the meshing tooth rows (25) being disposed at portions where the meshing tooth rows (25) face the inner and outer circumferential surfaces of the middle yoke member (15). The pair of magnetic meshing rings (151) and the pair of meshing tooth rows (25) are situated to be movable relative to each other between a facing position where the pair of magnetic meshing teeth (151b) and the pair of meshing teeth (25a) are positioned to face each other to cause the magnet member (152) to create a magnetic circuit between the magnetic meshing teeth (151b) and the meshing teeth (25a) and a not-facing position where the magnetic meshing teeth (151b) and the meshing teeth (25a) are positioned not to face each other.
    • 降低运行成本,同时防止产生噪音。 在中间轭构件(15)的内周面和外周面上并排配置有磁性啮合齿(151b)的一对磁性啮合环(151)。 位于所述一对磁性啮合环(151)之间的磁性构件(152),使得磁性啮合环(151)中的一个上的磁性啮合齿和另一个磁性啮合环(151)上的磁性啮合齿, 有相反的磁极; 以及一对啮合齿排(25),包括在内轭构件(21)的外周面上并排配置的多个啮合齿(25a)和外轭构件(22)的内周面, 并且面对所述磁性啮合环(151),所述啮合齿排(25)设置在所述啮合齿排(25)面对所述中间轭构件(15)的内周面和外周面的部分。 所述一对磁性啮合环(151)和所述一对啮合齿排(25)位于所述一对磁啮合齿(151b)与所述一对啮合齿(25a)之间的相对位置之间可相对于彼此移动 )被定位成彼此面对以使得磁性构件(152)在磁性啮合齿(151b)和啮合齿(25a)之间形成磁路,并且在磁性啮合齿(151b)和 啮合齿(25a)定位成不相对。
