PROBLEM TO BE SOLVED: To provide a cross wrench, in which component elements are securely fixed to each other to achieve high reliability and unit integrity performance, and a quantity of labor for manufacturing it is reduced. SOLUTION: The cross wrench comprises: a multi-angle rod part provided with a surface nut head at one end, and a force point at the other end, and having three fixing grooves; and an extension member provided with surface nut heads at both ends. In the extension member, at least three pairs of opening parts (each pair comprising two opening parts) which are partially crossing each other. A first opening part in each pair serves as an inserting hole for the multi-angle rod part, and a second opening part is provided with an adjusting push button clamp. COPYRIGHT: (C)2007,JPO&INPIT
