特徴を有する。To achieve the above object, according to the first aspect of the present invention, a primary connector having a primary coil unit is fitted to a secondary connector having a secondary coil unit. By this, both the primary and secondary cores provided in both coil units are brought into a butt state in the fitting direction, and in the electromagnetic induction type connector which can be magnetically coupled, the butt surface of the one core with the mating core is the same. It is characterized by being formed wider than the mating surface of the mating core.

量化できる。When the primary connector and the secondary connector are fitted together, both the primary and secondary cores are butted in the fitting direction and magnetically coupleable.
Here, if the connector is displaced by a clearance in a direction orthogonal to the fitting direction, the cores are displaced along the abutting surface. However, the butting surface of one core is wider than the butting surface of the mating core, so that the mating core is joined without protruding from the butting surface of the one core, and a minimum butting area is secured. Thus, power is stably transmitted between the primary connector and the secondary connector. Moreover, since only the mating surface of one core is widened and the other core does not need to be large,
The primary or secondary connector provided with the mating core can be reduced in size and weight.

Here, even if the connector is displaced by the clearance in the direction orthogonal to the fitting direction, the disk portion is formed wider than the distal end surface of the cylindrical portion.
The cylindrical portion is joined without protruding from the disk portion, and a minimum butted area is secured.
