1. A robot hand, comprising:
a base body defining a gripping position of a substrate;
a first contacting part provided to the base body at a tip-end side and configured to contact a first part of an edge part of the substrate when the substrate is gripped;
a rotary body provided on a base-end side of the base body and having a second contacting part configured to contact a second part of the edge part of the substrate when the substrate is gripped; and
a mobile body having a shaft part to be inserted into a shaft hole of the rotary body, and configured to move toward the tip end of the base body to move the rotary body toward the tip end of the base body,
wherein an axial-center line of the shaft part extends in a thickness direction of the base body, and the rotary body is provided so as to have a clearance in an axial direction of the shaft part with respect to the shaft part,
the robot hand further comprising a motion regulating part configured to regulate a motion of the rotary body in the axial direction by contacting an edge part of the rotary body in a state where the mobile body and the rotary body are moved toward the base end of the base body more than when the substrate is being gripped.
