Abstract
A torque transmission joint transmits torque between a drive shaft and a driven shaft. The torque transmission joint includes: a coupling including: a first concave-convex portion which is provided on one of inner and outer circumferential surfaces thereof and is engaged with a drive-side concave-convex portion of the drive shaft with a gap; and a second concave-convex portion which is provided on the other of the inner and outer circumferential surfaces and is engaged with a driven-side concave-convex portion of the driven shaft with a gap; a drive-side elastic member which is provided between the drive shaft and the coupling to be torque-transmittable; and a driven-side elastic member which is provided between the coupling and the driven shaft to be torque-transmittable. A concave-convex shape of the first concave-convex portion and a concave-convex shape of the second concave-convex portion are different from each other.
