Zusammenfassung:	The present invention provides a vehicle drum brake using parking levers that are reduced in size and ensure sufficient strength even though the thicknesses thereof are reduced. A first parking lever 60 and a second parking lever 70 that is joined to and rotates with the first parking lever 60 are provided. The first parking lever 60 and the second parking lever 70 are simultaneously engaged with a first strut member 54 at both sides of a shoe web 28 of a brake shoe 18. This makes the shapes of the first parking lever 60 and the second parking lever 70 compact. Furthermore, because the first parking lever 60 and the second parking lever 70 are formed of separate members, the thickness limitation imposed by bending is eliminated, and hence, strength is ensured.
