Patent

CA 2637076

A universal joint includes a base having a receiving recess and two holes defined through the base and communicating the receiving recess. A pivotal member includes a connection portion, a pivotal portion and a neck portion connected between the connection portion and the pivotal portion which is pivotably engaged with the receiving recess. A passage is defined through the pivotal portion and a pin extends through the two holes and the passage to pivotally connect the pivotal member to the base. The neck portion has a lowest point, and a shortest distance defined between the lowest point and a transverse line extending through an axial center line of the passage and perpendicular to the pivotal member is larger than a radius of the pivotal portion. The two respective distances between the lowest point and the transverse line extending through the axial center line of the passage and perpendicular to the pivotal member, and between the lowest point and the peripheral wall are longer so that the pivotal member can pivot larger angle and has better strength.
