The invention relates to a wrench available in a vehicle, more particularly, to a wrench for vehicles, which is a part of essential equipment (i.e. a jack, a jack actuation handle and a wrench) provided to all vehicles for tire changing, the wrench being designed to have, at one end thereof, a jack actuation handle for actuating the jack, thereby achieving cost reduction by using a smaller number of kit items. Thus, it is an object of the invention to provide tire changing equipment at a lower cost by reducing the number of tire changing tools provided to any manufactured vehicle. According to an embodiment of the invention, a wrench consisting of a head at one end thereof and a handle at the other end thereof comprises an actuating pipe which includes: a connecting pipe with an inner diameter to be joined to the wrench handle; an enlarged pipe prepared by enlarging one side of the connecting pipe so as to have an enlarged inner diameter; and an actuating member joint provided with notching pieces on both lateral sides, the notching pieces being prepared by arranging narrow notches in laterally symmetric positions on the tip end of the enlarged pipe, and with a locking hole passing through the central portions of the notching pieces on both lateral sides, wherein the connecting pipe formed at one end of the actuating pipe is coupled to and fixed to the wrench handle. |
