A crutch, which does not give pressure on the tissues, muscles and nerves of the user's armpit, and provides a stabilized walking to a user, is disclosed. The crutch includes a support rod, a cross-pad coupled to an upper end of the support rod, a hand piece provided at a mid point of the support rode, and a cap for preventing the crutch from skidding mounted on a lower end of the support rod. An upper part corresponding to a section between the cross-pad and a predetermined point below the hand piece of the support rod is curved to have a smaller radius, while a lower part corresponding to a section between the predetermined point of the support rod and the lower end of the support rod is curved to have a larger radius.
