The abutment and interlocking spring 9 is used which is capable of being tilted in conjunction with the tilting of the movable bodies 5, 5 a and 5 b and is slidable in the longitudinal direction. Instead of the contact / interlock spring 9, a contact / tilt spring can be used.
Hereinafter, as a fourth embodiment of the present invention, a charging device using a protruding and pushing spring and a contact / tilting spring will be described with reference to FIG.

FIG. 19 is a diagram corresponding to FIG. 10 in the first embodiment. The same components as those in FIG. 10 are denoted by the same reference numerals and description thereof is omitted, and the components different from FIG. 10 are described in detail. To do.
As shown in FIG. 19, the abutment / tilting spring 15 has one end 15 a fixed to a rib 32 b formed integrally with the case bottom plate 32, and an intermediate coil-shaped portion 15 b is formed in the axial shape of the second movable body 6. The other end 15c is wound around the support portion 62 and fixed to one end side 65 of the second movable body 6, and the upper contact portion 63 of the second movable body 6 is connected to the lower contact portion of the first movable body 5c. It is urged so that it abuts on top of 53, and is urged so that it can be tilted and slidable in the longitudinal direction in conjunction with the tilt of the first movable body 5c.

The abutment / tilting spring 15 is attached so that the protruding pressing portion 51 of the first movable body 5c protrudes outside the mounting portion 2 when the electronic device 71 is not mounted on the mounting portion 2. And when the electronic device 71 is mounted on the mounting portion 2, the first movable body 5c and the first movable body 5c are overcome by overcoming the biasing force of the abutment and tilting spring 15 when the electronic device 71 is mounted on the mounting portion 2. The second movable body 6 is tilted to bring the pair of power supply terminals 4 into contact with the pair of charging terminals 72 of the electronic device 71 to charge the built-in battery of the electronic device 71.
The spring constant of the abutment / tilting spring 15 is made larger in consideration of the spring constant of the protruding pusher spring 8 removed than the spring constant of the abutment / interlocking spring 9 in the first embodiment. .

Further, since the protrusion pressing portion spring 8 of the first movable body 5 in the first embodiment is removed, the shape of the support portion 52a of the first movable body 5c is simplified in the fourth embodiment. .
In the fourth embodiment described above, since the protruding pressing portion spring can be removed, the number of parts can be reduced, and manufacturing and assembly can be performed more easily.

In the fourth embodiment described above, the protruding pressing portion spring 8 in the first embodiment is removed, but the protruding pressing portion spring 8 in the second and third embodiments may be removed. Of course.
In the above first to fourth embodiments, a mobile phone has been described as an example of the electronic device 71. However, the electronic device 71 can be various portable electronic devices.
