Further, by setting the second meshing teeth 15 and 17 to be smaller in number than the first meshing teeth 11 and 13, the circumferential pitch of the second meshing teeth 15 and 17 is increased, and the inner case 3 and Even if the differential rotation with the cam ring 5 is large, the second meshing teeth 15 and 17 can be sufficiently meshed. Such second meshing teeth 15, 17 are arranged so that when the second meshing teeth 15, 17 are meshed, the first meshing teeth 11, 13 are located at positions where they can mesh with each other. The cam ring 5 is provided. The cam ring 5 provided with such a meshing portion 7 is moved by an actuator 9. It is possible to reduce the surface pressure acting on the meshing teeth 17 by providing the meshing teeth 17 radially outward from the meshing teeth 13.

  The actuator 9 includes an electromagnet 35 and a movable member 37. The electromagnet 35 is prevented from rotating in the rotational direction with respect to a stationary system member such as a carrier by a non-rotating member (not shown) or the like, and includes an electromagnetic coil 39 and a core 41. The electromagnetic coil 39 is molded with resin and accommodated in the core 41. The core 41 is made of a magnetic material and is connected to a controller (not shown), and energization of the electromagnetic coil 39 is controlled by the controller. A movable member 37 is disposed on the inner diameter side of the electromagnet 35, and the movable member 37 is moved by energizing the electromagnet 35.

  The movable member 37 is axially movable and radially supported on the outer periphery of the support member 45 that is positioned in the axial direction on the outer periphery of the boss portion 209 of the outer case 203 by a fixing member 43 such as a snap ring.

The meshing phases are aligned in the circumferential direction by the meshing of the second meshing teeth 15, 17, and the first meshing teeth 11, 13 are positioned at a meshable position. Next, when the cam ring 5 is further moved in the meshing direction of the meshing portion 7 from the state where the second meshing teeth 15 and 17 are meshed with each other, the first meshing teeth 11 and 13 mesh with each other. As a result of the meshing of the first meshing teeth 11 and 13, the inner case 3 and the cam ring 5 are connected so as to be integrally rotatable, and when the driving torque is received by the torque cam mechanism 23, the meshing portion 7 is tightened more strongly. Power transmission between the case 3 and the outer case 203 is possible.

Since there are second meshing teeth 15 and 17 that mesh with each other to position the first meshing teeth 11 and 13 so that they can mesh with each other, even if the differential rotation between the inner case 3 and the cam ring 5 is large, the first meshing teeth 11 The first meshing teeth 11 and 13 can be meshed with each other by meshing the second meshing teeth 15 and 17 before meshing with each other. In addition, chattering of the meshing portion 7 can be prevented.

  For this reason, even if the differential rotation between the inner case 3 and the cam ring 5 is large, the first meshing teeth 11 and 13 do not mesh at a position where they cannot mesh, and damage at the meshing portion 7 can be prevented. In addition, since the first meshing teeth 11 and 13 can be reliably meshed with each other, power transmission between the inner case 3 and the cam ring 5 can be stabilized.

  Further, since the second meshing teeth 15 and 17 are formed at least one place in the circumferential direction on the inner case 3 and the cam ring 5, respectively, the shape of the inner case 3 and the cam ring 5 is not complicated, and the structure of the apparatus Can be simplified.

  Accordingly, even if the differential rotation of the inner case 3 and the cam ring 5 is large, the meshing portion 7 can be meshed with a simple structure.

  Further, the protrusion height h2 of the cam ring 5 in the engagement direction of the second engagement teeth 17 is set higher than the protrusion height h1 of the first engagement teeth 11 and 13 in the engagement direction. Before the meshing teeth 15 and 17 mesh with each other, the first meshing teeth 11 and 13 do not interfere with each other, and the second meshing teeth 15 and 17 reliably position the first meshing teeth 11 and 13 so that they can mesh with each other. be able to.

  Further, since the respective meshing surfaces 19 and 21 of the first meshing teeth 11 and 13 and the second meshing teeth 15 and 17 are continuously provided in the circumferential direction of the inner case 3 and the cam ring 5, The second meshing teeth 15 and 17 can be provided by simply changing the design of at least one of the first meshing teeth 11 and 13 formed in the circumferential direction in the case 3 and the cam ring 5.

  Further, since the first meshing teeth 11 and 13 and the second meshing teeth 15 and 17 are provided at different radial positions in the inner case 3 and the cam ring 5, a plurality of first meshing teeth 11 and 13 are formed in the circumferential direction. The second meshing teeth 15 and 17 can be provided only by changing the radial position of at least one of the meshing teeth 11 and 13 to the inner diameter side or the outer diameter side.

  Furthermore, since the cam ring 5 is provided with a torque cam mechanism 23 that moves the cam ring 5 in the meshing direction when the first meshing teeth 11, 13 are meshed with the cam ring 5, the meshing of the first meshing teeth 11, 13 is made stronger. can do.
