DETAILED DESCRIPTION OF ILLUSTRATIVE EMBODIMENTS

From the viewpoint of a compact electric vehicle charger used in charging an electric vehicle, a plug-in hybrid vehicle, etc., it is requested to compact and store a charging connector and a charging cable in a unitary construction. However, it is common that an electric vehicle charger 1 is designed longer with enough length to be laid on the ground with sufficient slack during the charging operation. Therefore, the charging cable is subject to stains of soil, water, etc., and when a charging connector and a charging cable are stored together, the stains of soil, water, etc. on the charging cable adheres to the handle unit and the connector unit, which prevents appropriate charging operation. The stains of soil, water, etc. adheres to the connector unit is causes fault in the electric vehicle charger. Then, an electric vehicle charger is devised as having a charging cable winder unit for winding and holding the charging cable and a charging connector holding unit for holding the charging connector so that the charging connector is directed in the same direction as the winding direction of the charging cable with a partition for separating the charging connector holding unit from the charging cable winder unit.

However, if the winding direction of the charging cable is fixed as one direction, inconvenience for a user is anticipated. That is, depending on, for example, the dominant hand of a user, the winding direction of the charging cable can be different by each user. Therefore, a fixed winding direction will cause the inconvenience for a user. Furthermore, a different winding direction of the charging cable is anticipated by the location of the electric vehicle charger.

In the situation above, using the electric vehicle charger having: a first winder unit and a second winder unit for winding and holding a charging cable provided with a charging connector at its end portion; and a body unit having an arrangement of the first winder unit and the second winder unit with the distance between the first winder unit and the second winder unit longer than the diameter of the charging cable, the charging cable passes between the first winder unit and the second winder unit, and the charging cable is fixed before the passage between the first winder unit and the second winder unit. As a result, the charging cable can be wound in a preferable direction, and a use can appropriately perform the charging operation.

The embodiment is described below in detail with reference to the attached drawings.

The embodiment 1 is described below.
