Abstract
A metal sheet is cut to provide an elongated blank having five regions defined along the length of the elongated blank, the defined regions being a central region, two end regions, and an intermediate region between the central region and each of the two end regions. The elongated blank is bent such that the two end regions overlap and provide a mounting for a shaft and such that a pivot member to be mounted on the central region of the elongated blank will be in alignment, axially, with respect to the shaft. Bores may be formed in the intermediate regions for mounting of a cross-piece to pivotably connect the yoke to a coupling member.

A yoke for a double Cardan universal joint, the yoke comprising:
- an elongated blank with five regions defined along the length of the elongated blank, the defined regions being a central region, two end regions, and an intermediate region located between the central region and each of the two end regions;
- each end region having an end bore having a respective end bore central axis and the central region having a pivot member mount having a pivot member mount central axis;
- and
- the elongated blank being bent such that the two end regions of the elongated blank overlap with the end bore central axes in substantial alignment to define a shaft mount bore through both end regions, the shaft mount bore having a shaft mount bore central axis substantially co-axial with the pivot member mount central axis such that a pivot member to be mounted on the central region of the elongated blank will be in axial alignment with respect to a shaft to be mounted through the shaft mount bore.
