It is composed of a second guide hole (33b) having a space.

In this case, the first guide hole 33a is formed to have a constant length.

In addition, the expansion space of the second guide hole (33b) may be formed in a form in which the space is expanded downward as shown in the accompanying FIG. It is also possible to be configured to form a box-shaped space in a vertical form after the space is expanded. However, in any case, it is preferable that the second guide hole be manufactured in the form of the widest space at the lower end.

Therefore, during the elevating operation by the operating means 20, the guide bar 35 also elevates and lowers together with the guide block 22. When the guide bar 35 is located in the first guide hole 33a, Only the lifting operation is implemented, and when the guide bar 35 is located in the second guide hole 33b, not only the lifting operation but also the turning operation of a certain angle is possible.

Therefore, when the charging device is not used, the guide bar 35 is positioned at the uppermost end of the first guide hole 33a so that the rotation of the operating means 20 is limited. Conversely, when charging using a charging device, the guide bar 35 descends to the bottom of the second guide hole 33b, and the user moves the charging cable (CC) or the charging gun to the charging socket position of the electric vehicle. The operation means 20 is capable of turning within the range of the rotation angle, so that it is possible to secure the fluidity of the charging cable (CC). In this case, the turning operation of the operating means 20 is to enable free rotation by the first and second rotating parts 28 and 29 when the user moves the charging gun.

In addition, when the charging is finished, the guide bar 35 of the angle adjusting means also rises by driving the operation means 20, which is the guide bar 35 moving from the second guide hole 33b to the first guide hole 33a. means to rise. In this case, in order to facilitate the inflow of the guide bar 35 from the second guide hole 33b to the first guide hole 33a, the shape of the second guide hole 33b is formed to become narrower toward the upper side. It is preferable that the upper end of the ball 33b and the lower end of the first guide hole 33a have the same width. By doing this, the guide bar 35 rising from the second guide hole 33b has a structure that naturally flows into the first guide hole 33a.

This is because the point at which charging is terminated can be terminated at any point at the lower end of the second guide hole 33b depending on the pivoted position of the charging cable CC, so the guide bar 35 ascending and descending at this point rises as the second On both sides of the guide hole 33b, that is, on the inclined surface, natural entry into the first guide hole 33a can be induced. Therefore, it is preferable that the second guide hole 33b is formed in the shape of an upper and lower light as shown in FIG. 6 .
