To provide a joint constriction for pile having a sufficient durability against impact for axial tension force and being capable of obtaining a high torque transmitting force in rotating direction.

This joint construction comprises a pair of joint blocks 12 respectively fixed to the joint surfaces of the end portion of pile 10. Each joint block 12 is located at the inner side of a substrate 14 seated at the pipe end face, an outer peripheral portion 16 raised in one united body from the peripheral edge of the substrate 14 with a semi-spherical shape, and the outer peripheral wall portion 16 and comprises a cylindrical portion 18 raised in one united body from the substrate with a rising dimension half of the above, a projected stripe 20 stuck out and formed in the upper inner periphery of an outer peripheral wall portion 16, and a recessed groove 22 formed in a peripheral shape around the outer periphery with half periphery exposed of the cylindrical portion 18. In a state where the joint blocks 12 are lapped together, end faces of the cylindrical portion 18 are butted each other, outer peripheral wall portions 16 have a hook shape and linked in a direction of whirl-stop, and a projected stripe 20 and a recessed groove 22 facing each other are linked and coupled in axial direction.
