とを特徴とするプリロード調整装置。 A screw member is tightened to a shaft member rotatably supported by a support member via a bearing to apply a required preload to the bearing, and the shaft member is rotated so that the support member is rotated as the shaft member rotates. A preload adjustment device that measures preload by co-rotation, the device comprising: a drive means capable of forward and reverse rotation for tightening the screw member; and a drive means arranged concentrically around the outer periphery of the drive means and engaged with the shaft member. The rotary engaging member is rotatably supported, and when the screw member is tightened by normal rotation of the driving means, rotation of the rotary engaging member is prevented, and the driving means A clutch mechanism that allows rotation of the rotating engagement member when measuring preload due to reversal of the shaft member, and a detection means that measures preload by rotating the support member as the shaft member rotates when measuring the preload. A preload adjustment device characterized by:
