Abstract
An erroneous assembling preventing tool for a universal joint prevents a shaft from being fixed to a cylindrical section of a yoke main body of the universal joint by fastening a bolt in a state where the shaft is not inserted into a normal position of an axial direction of the cylindrical section. The erroneous assembling preventing tool comprises a fixing section fixed to the yoke main body, a prevention section arranged between first and second tabs of the yoke main body, and a driving section for driving a prevention section. The prevention section is displaceable to a prevention position at which an end of the bolt can be prevented from being inserted through a screw hole of the second tab of the yoke and a prevention release position. The driving section displaces the prevention section to the prevention release position when it is pressed by an end of the shaft inserted into the normal position of the axial direction of the cylindrical section.
