An electromagnetic absorber (10) for a vehicle including (a) a threaded rod (78) which is disposed on one of a sprung portion and an unsprung portion and which has a threaded groove (76) formed in its outer circumferential portion and an axial groove (90) extending in its axis direction (b) a nut (80) which is rotatably disposed on the other of the sprung portion and the unsprung portion and which is screwed with the threaded rod and (c) a rod-rotation inhibiting member (82) which includes a fitting portion configured to be fitted in the axial groove and which is disposed on the other of the sprung portion and the unsprung portion, the rod-rotation inhibiting member being configured to inhibit the threaded rod from rotating while permitting the threaded rod to move in the axis direction. In the electromagnetic absorber, the threaded groove is not formed at a section of a fitting range at which the fitting portion is fitted in the axial groove when the fitting portion is located at an end of the fitting range that extends in the axis direction on the outer circumferential portion of the threaded rod.
