1. An autonomous travel working machine capable of traveling to a charging station by autonomous travel, the autonomous travel working machine comprising:
a vehicle body having a traveling function, and a pair of power receiving terminals to be electrically connected to the charging station, wherein
one of the pair of power receiving terminals is provided on a surface of the autonomous travel working machine, and the other is provided in a position where the other sandwiches at least a part of the vehicle body with the one power receiving terminal,
wherein the one power receiving terminal has an upward-facing contact surface in contact with the charging station, and
wherein the contact surface is an inclined surface that is inclined obliquely with respect to a horizontal plane.
