Abstract
A universal joint composed of a swivel member, a driven socket, and at least one mediator. The swivel member includes a swivel body and a first driving portion. The driven socket includes a concavity, a second driving portion, and an annular recess formed at the concavity. A retaining ring is mounted in the annular recess. The swivel body is received in the concavity. The swivel body includes at least one cavity formed on a surface thereof. The driven socket includes at least one recession, which can correspond to the at least one cavity when the swivel body is located in the concavity. The at least one mediator interacts with the recession and the cavity and is located between the swivel body and the driven socket. Therefore, the operation of the universal joint can be smooth.
