[Problem] To provide a method of manufacturing a vehicular traction apparatus, which is suited to, for example, an automobile traction apparatus and mounted with a hook portion of a traction hook in a predetermined orientation to a connecting member on a side of an automobile, and in which generation of rolling and looseness of the traction hook by vibrations and an external force at the time of traction is prevented, reliability and safety in traction are ensured, the traction hook is smoothly mounted to the connecting member, and it is possible to increase the parts in strength, to make them small in size and weight, to facilitate processing them, and to manufacture them at low cost, and a vehicular traction hook, and a method of manufacturing a vehicular connecting member. [Means for Resolution] Providing a connecting member 8 having a female thread portion 9 that can be mounted to a vehicular side,
providing a traction hook 1 provided at one end thereof with a male thread portion 4 that can be screwed into the female thread portion 9, and provided at the other end thereof with a hook portion 3, to which a traction member W can be mounted,
a vehicular traction apparatus,
arranging an original position Ss and/or a terminal position Se of the male thread portion 4 of the traction hook 1 in predetermined positions relative to the hook portion 3, and
enabling setting, after the male thread portion 4 is clamped to the connecting member 8, a position of the hook portion 3 in a predetermined, allowable angle position ¸. |
