1. A horizontal shaft rotor comprising:
a hub and a plurality of blades facing in a radial direction and fixed to a peripheral surface of the hub,
wherein a distal part from a radial direction middle part of each of the plurality of blades has a forward curved part,
a front end surface of a forward tip of the forward curved part is a lift type in which a leading edge side of the front end surface is thicker than a trailing edge side of the front end surface, in a front view,
at least a line extending along the front end surface, located at the forward tip of the forward curved part remote from the hub, is orthogonal to an axis center line of the hub, and
a maximum thickness of the front end surface at the forward tip of the forward curved part is set to be 50% of a thickness of a base end part of a base part.
