  However, even if the battery box is held so as to wrap the battery without any gaps as described above, it is difficult to completely prevent foreign matter and water from entering the battery box. Water tends to accumulate. For this reason, when the connection terminal on the battery box side is arranged at the bottom of the battery box, there is a drawback that the foreign matter and water adhere to the connection terminals and cause a contact failure between the connection terminals.

  In addition, if the gap between the battery and the battery box is narrowed as described above, the battery may be accidentally inserted into the battery box with the operator's hand or finger placed on the opening edge of the battery box when replacing the battery. If the battery is inserted or dropped, a hand or a finger may be caught between the opening edge of the battery box and the battery, and the operator may be injured. In particular, when the space below the driver's seat is used as a battery box as in Patent Document 1, the height of the opening edge of the battery box is just high enough for the operator to place his / her hand. The possibility of pinching hands and fingers increases. Therefore, some countermeasure is necessary.

  In view of the above circumstances, an object of the present invention is to prevent an operator from being injured by putting a hand or a finger between a battery and a battery box.

  The present invention relates to a battery box for an electric motorcycle that travels using electric power from a battery as a power source, and includes an upward opening and a battery storage section in which the battery can be inserted and removed, along an opening edge of the battery storage section. And an elastically deformable cushion member provided.

The battery housing portion side terminal connectable to the battery side terminal is provided in the concave portion, and the cushion member may be provided along the opening edge corresponding to the concave portion.

  By adopting such a configuration, even if foreign matter or water accumulates at the bottom of the battery storage unit, it is possible to prevent the foreign matter or water from adhering to the battery side terminal or the battery storage unit side terminal. In addition, poor contact between terminals can be prevented.

  Further, the upper end surface of the battery storage portion may be cut out to the vicinity of the bottom surface of the concave portion, and the cushion member may be disposed in the cutout portion.

  In this way, by disposing the cushion member in the recess provided in the upper end surface of the battery storage unit, the cushion member is disposed on the upper end surface of the battery storage unit not provided with the recess. The lower end can be set at a low position. Therefore, if the position of the upper end portion of the cushion member is the same, the vertical width of the cushion member can be increased, and as a result, the upper end portion and the opening edge portion of the cushion member can be moved away. Therefore, it is possible to prevent the operator from sandwiching a hand or a finger between the opening edge portion and the battery, and it is possible to further improve safety.
