In the above embodiment, the example in which the stage 8 is arranged inside the opening 39 has been described, but the present invention is not limited to this. For example, the stage 8 may be arranged outside the opening 39.

In the above embodiment, the buffer mechanism 10 and the guide mechanism 11 are provided separately and independently, but the present invention is not limited to this. For example, the buffer mechanism 10 and the guide mechanism 11 may be provided integrally. For example, the shock absorbing mechanism 10 may have a shock absorbing function of the battery 45 and a guiding function of the stage 8.

In the above embodiment, the protection unit 12 has been described with reference to an example in which the protection unit 12 can rotate around an axis extending in the first direction (left-right direction) parallel to the installation surface FL, but the present invention is not limited to this. For example, the protection unit 12 may be rotatable around an axis extending in a second direction (vertical or front-back direction) intersecting the first direction. That is, the protection unit 12 may be rotatable around an axis extending in the first direction parallel to the installation surface FL on which the charger 1 is installed, or in the second direction intersecting the first direction.

In the above embodiment, the example in which the protection unit main body 120 can rotate around the axis has been described, but the present invention is not limited to this. For example, the protection unit main body 120 may be slidable along the lower surface of the stage 8. That is, the protection unit main body 120 covers the terminal opening 80 when the battery 45 is not mounted on the stage 8 (initial state), and moves in conjunction with the stage 8 when the battery 45 is mounted on the stage 8. , The terminal opening 80 may be exposed.

In the above embodiment, the protection unit 12 includes a protection unit main body 120 that covers the terminal opening 80 without mounting the battery 45 on the stage 8, and a pair of protection legs 121 that extend outward from the protection unit main body 120. Although the explanation has been given with an example of including the urging member 122 for urging the protective leg portion 121, the present invention is not limited to this. For example, as shown in FIG. 14, the protection unit 212 slides the protection unit main body 120 that covers the terminal opening 80 and the protection unit main body 120 along the lower surface of the stage 8 without mounting the battery 45 on the stage 8. The slide mechanism 230 may be provided.

In the example of FIG. 14, the slide mechanism 230 is attached to the L-shaped main body support portion 231 and the main body support portion 231 attached to the front right side of the protective portion main body 120 in a state where the battery 45 is not mounted on the stage 8. The first shaft 232, which is rotatably inserted and extends in the first direction (left-right direction), and the upper end portion are supported by the right end of the first shaft 232, and are located downward toward the rear in the side view (initial state) of FIG. With an arm portion 233 that is inclined and extends linearly, a second shaft 234 that is rotatably inserted through the lower end portion of the arm portion 233 and extends parallel to the first shaft 232, and an arm that urges the arm portion 233. A force member 235 and a guide plate 236 for guiding the main body support portion 231 are provided. In FIG. 16, the protective portion 212 at the position in the initial state is shown by a chain double-dashed line.

In this modification, the arm urging member 235 is a torsion spring. The arm urging member 235 constantly urges the arm portion 233 in a direction opposite to the rotation direction R1 around the second shaft 234. The guide plate 236 is provided with a slit 237 extending along the slide direction S1 of the protection unit main body 120.

With the battery 45 not mounted on the stage 8, the arm portion 233 is linearly inclined so as to be located in a direction closer to the terminal portion 9 (see FIG. 5) toward the lower side. When the battery 45 is placed on the stage 8, the protection unit main body 120 slides along the lower surface of the stage 8 against the urging force of the arm urging member 235. In FIG. 16, reference numeral S1 indicates the sliding direction of the protection unit main body 120. When the protection unit main body 120 slides in the direction of arrow S1, the terminal opening 80 is exposed (see FIG. 15).

In the above embodiment, an example in which the urging member is a torsion spring has been described, but the present invention is not limited to this. For example, the urging member may be a spring other than a torsion spring such as a leaf spring or a spiral spring. For example, the urging member may be an elastic body such as rubber. That is, the urging member may have an urging force that acts in the direction of maintaining the state in which the protective portion covers the terminal opening 80.

In the above embodiment, the slider 110 has been described with reference to an example in which the slider 110 is fixed to the first downward extending portion 92 and the second downward extending portion 93 of the stage support 90, but the present invention is not limited to this. For example, as shown in FIG. 17, the stage peripheral component 209 including the slider 210 may be integrally molded. For example, a resin material is used as the forming material for the stage peripheral component 209. In FIG. 17, reference numeral 210 indicates a slider, reference numeral 211 indicates a support portion on the rod that supports the upper end of the piston rod 100, and reference numeral 212 indicates a frame wall having a rectangular frame shape along the outer shape of the stage 8 (see FIG. 18).

In this modification, the stage 8 (see FIG. 18), the slider 210, the rod upper support portion 211, and the frame wall 212 are integrally formed of the same member. That is, the stage 8 and the stage peripheral component 209 are integrally formed of the same member. This simplifies the peripheral structure including the stage 8 and facilitates the assembly of the charger.

In FIG. 17, reference numeral 220 indicates a downward extending wall extending downward from the four corners of the cover body 40. The downward extending wall 220 is arranged inside the frame wall 212. The downward extending wall 220 functions as a guide wall for guiding the vertical movement of the stage 8 via the frame wall 212. In FIG. 17, the stage peripheral component 209 in the initial state is shown by a solid line, and the stage peripheral component 209 located close to the battery chamber bottom wall (board chamber upper wall 250) is shown by a chain double-dashed line.

In FIG. 18, the stage 8 (the state located at the uppermost position) in the position of the initial state is shown. FIG. 19 shows a state in which the stage 8 has moved to the lowermost position.
