Abstract: A ski-equipped crutch comprising a pole member, a pole-ski member detachably secured to the bottom of said pole member, and a holding member secured to the pole member and said pole-ski member to hold these two members so as to allow rotation of these two members relative to each other. Said holding member has an upright guide plate provided with an arcuate edge having spaced notches for selective engagement with a movable ball housed in said pole member and urged toward said arcuate edge by a spring. Said pole member further has a length-adjusting means comprising at least two separate portions one of which is received in the other and also comprising means for fastening these two portions tightly together at a desired position of these two portions selected from given positions. By loosening this fastening means, the pole member can be separated into parts for the convenience of transportation of the crutch.
