An object of the design is a seal for a drive shaft of a vehicle that is made of rubber; the seal is inserted into a through hole of a tubular outer shaft of a plunging-type drive shaft that is used in a drive system of a vehicle: the seal prevents grease for a ball spline mechanism for a plunging movement of a drive shaft from being leaked via a through hole of a tubular outer shaft and also prevents air flow via a through hole.
