An automatic tool exchange coupler and an automatic tool exchange device are provided that achieve further improvement in the user-friendliness of the automatic tool exchange device. The coupler includes a coupler body, a first direction switching valve and a second direction switching valve that are provided to a first side surface of the coupler body. The coupler body has: in a first side surface, an uncoupling input port being connected to a pipe for introducing a gas for uncoupling; and in the second side surface opposite to the first side surface, an uncoupling output port being configured to connected to the uncoupling port. The uncoupling input port is located at a position where a center of the uncoupling input port is radially offset with respect to the uncoupling output port by at least an amount corresponding to a length of a diameter of the uncoupling input port.
