A joint assembly interconnecting first and second rotatable shafts includes an engaging member mounted on a shaft portion of the first rotatable shaft, a tubular assembly including a first tubular member in which the shaft portion is coaxially inserted and which has an engaged member for engaging the engaging member, and a second tubular member coupled to the second rotatable shaft, and an urging assembly disposed in the first tubular member for normally urging the first tubular member and the first rotatable shaft axially away from each other to keep the engaging member and the engaged member in engagement with each other. The engaged member has a central through hole through which the first rotatable shaft is inserted, and holes extending radially from the central through holes for allowing the engaging member to be axially inserted therethrough, for thereby permitting the first rotatable shaft to be connected to and disconnected from the joint assembly. |
