A brake lining includes a mounting plate, sliding members and elastic members. The sliding members are arranged in the transverse direction and the longitudinal direction of the mounting plate on one surface of the mounting plate to form transverse rows and longitudinal rows. The elastic members are provided in correspondence with the sliding members. Each of the elastic members is disposed between the corresponding sliding member and the mounting plate. A gap exists between adjacent transverse rows, and extends over the entire length of the transverse rows. A gap exists between adjacent longitudinal rows, and extends over the entire length of the longitudinal rows. The gap has a width that is smaller than a width of the gap.

The lining assembly includes a friction material and a back plate portion. A plate fitting portion of the lining assembly is inserted and equipped to a guide hole portion, and braking torque is transmitted from the plate fitting portion to the guide plate. A plurality of link plates applying pressing force from a torque receiving plate to the lining assembly are provided between the torque receiving plate and the back plate portion adhered to the guide plate. A damping layer sandwiched between inner surfaces of the torque receiving plate is provided on back surface sides of the link plates.

In a carrier disk assembly for a brake assembly, and an electromagnetically actuable brake assembly with a carrier disk assembly, the carrier disk assembly has a hub part, two friction linings, and two disks. The disks are connected to the hub part, in particular with the aid of axially directed screws. Each one of the disks has a surface region provided with first depressions. A first friction lining is bonded and/or glued to the first disk in the surface region of the first of the two disks, and a second friction lining is bonded and/or glued to the second disk in the surface region of the second of the two disks.

Provided are a joint component formed with fine recessed portions, a multiplate clutch device including the joint component, and a joint component manufacturing method. At the joint component, many fine recessed portions are formed at a joint surface joined to a joint object. The joint surface is formed in a circular ring shape along a peripheral direction of the base body, and is formed with a flatness of equal to or less than 0.15 mm. The fine recessed portions are formed at the joint surface such that adjacent ones of the fine recessed portions do not overlap with each other and a formation density per unit area at the joint surface is uniform. The fine recessed portions are formed as laser processing marks formed at the base body by irradiation with laser light.
