Abstract
A disk brake that includes, between an internal gear () and a first housing portion () of a housing (), each of protrusion portions () provided on the internal gear side and engagement recessed portions () provided on the first housing side that are engaged with each other to restrict a relative rotation. Each of these protrusion portions on the internal gear side and engagement recessed portions on the first housing portion side are disposed along a direction perpendicular to a straight line connecting a radial center of a second speed reduction gear () and a radial center of a first speed reduction gear (). Due to this configuration, the disk brake can improve the precision of the position of the internal gear of the planetary gear speed reduction mechanism () while reducing the cost.
