To provide a universal joint which can suppress the generation of rust at a spider, and can be easily manufactured.SOLUTION: A universal joint comprises a spider and a seal member. The spider comprises a main body part, a first shaft part protruding from the main body part, a second shaft part protruding from the main body part in a second direction orthogonal to a first direction being an axial direction of the first shaft part, a third shaft part protruding from the main body part in a direction reverse to the first shaft part, and a fourth shaft part protruding from the main body part in a direction reverse to the second shaft part. The seal member is attached to the spider. The seal member comprises a base part for covering the main body part, and contacting with the main body part. The base part comprises a first hole which the first shaft part penetrates, a second hole which the second shaft part penetrates, a third hole which the third shaft part penetrates, a fourth hole which the fourth shaft part penetrates, and a fifth hole penetrating in a third direction which is orthogonal to both the first direction and the second direction.SELECTED DRAWING: Figure 11
