Abstract:
1. A disk brake for a vehicle, the disk brake comprising: a mounting member having a pair of arms spaced apart from each other in a rotational direction of a disk, said arms extending over an outer periphery of said disk in an axial direction of said disk, said arms being provided with pad guides; a caliper slidably provided on said mounting member; a pair of friction pads slidably mounted on the arms of said mounting member through said pad guides so that said friction pads are pressed against both sides of said disk by said caliper; and an entrance-side pad spring attached to one arm of the arms of the mounting member and an exit-side pad spring attached to the other arm of the arms of the mounting member, said one arm being the arm at the entrance-side of the disk brake in a rotational direction of the disk when the vehicle runs forward, said other arm being the arm at the exit-side of the disk brake in the rotational direction of the disk when the vehicle runs forward, said entrance-side pad spring and said exit-side pad spring resiliently supporting said friction pads between said arms; wherein said entrance-side pad spring includes: guide plate portions fitted to the associated pad guides of said mounting member to guide said friction pads axially of said disk in cooperation with said pad guides; and circumferentially urging portions formed as wide plate-shaped members which are bent from said guide plate portions obliquely radially inward of said disk so that the wide plate-shaped members can abut against one side of each of said friction pads and urge said friction pads in the rotational direction of said disk, whereby the wide plate-shaped members constantly urge the other side of each of said friction pads against said exit-side pad spring, and wherein said exit-side pad spring does not urge said friction pads in the rotational direction of said disk.
