PROBLEM TO BE SOLVED: To provide a joint fixture for wooden building requiring no time to perform drilling work while reducing cost by reducing the number of parts and simplifying the shape of each part. SOLUTION: The fixture A comprises a plate 1 and protruding parts 2 protrusively provided at the side part of the plate 1. The protruding part 2 is provided with through holes 20 extending in an orthogonal direction to a plane of the plate; a pair of cutting edge metals 41, 42 movably arranged in the through holes 20 so that cutting edge parts 41b, 42b can protrude from the through holes 20 of the protruding part 2; a pair of insertion holes 21, 22 communicating with the through holes 20 from the base end side of the protruding part 2; and wedges 30 driven into the insertion holes 21, 22 from the base end side of the protruding part 2 to push away the base end side of the cutting edge metals 41, 42 so that the cutting edge parts 41b, 42b of the cutting edge metals 41, 42 project from the through holes 20. In the state of the wedges 30 being driven into the insertion holes 21, 22, the cutting edge parts 41b, 42b protrude from the through holes 20 and bite into a wood member 50.
