Abstract: A sport glove is such that a notched portion that also serves as hand insertion portion is provided at a lower portion of the back portion in such fashion as to cover neither the radiocarpal joint nor the midcarpal joint of the wearer, a tip end portion of a tightenable strap being removably retained at the back portion, and a base end of the tightenable strap being secured to a side end of the pinky finger sheath portion at the palm portion, in such fashion that neither the radiocarpal joint nor the midcarpal joint is covered by the tightenable strap. Because neither the radiocarpal joint nor the midcarpal joint—these carrying out flexion and extension and lateral bending of the hand of the wearer—is covered, there is no occurrence of sensation of pressure from the back of the glove to these joints.
