A hand protector used in recuperation process is made of a plastic material, including a palm-supporting member, and a finger-supporting member pivotally connected with the palm-supporting member. The hand protector can further be added with a wrist-supporting member connected rearward with the palm-supporting member. Thus, a user can use a hand protector of a proper length according to different sections of the hand to be recuperated, supporting the different sections of the hand in the stable normal condition, and with the pivotal connection enabling the joints of the hand to swing freely for stimulating smooth circulation of blood so as to prevent the hand from deforming or suffering from atrophy to obtain the best effect of recuperation.
