Abstract: This disk brake includes an attachment member that has support portions movably supporting a pair of brake pads, and a caliper that pressurizes the brake pads against a disk. The attachment member has outer circumferential frame portions, a coupling beam portion, and support main body portions. The outer circumferential frame portions extend in a disk circumferential direction so as to cover the disk while straddling the disk. The coupling beam portion couples the support portions to each other. The support main body portions form the support portions. The outer frame constituting portions constitute the outer frames of the support main body portions. Positions of disk-axially outward side end surfaces in a disk axial direction are the same as positions of the disk-axially outward side end surfaces of the caliper or on sides outward in the disk axial direction.

Abstract: A biometric authentication device including a housing, a light source unit that is installed on an upper surface of the housing and includes a light source, and an opening that is provided in the upper surface of the housing and located below the light source, and an imaging unit that is disposed inside the housing is disclosed. In the device, an optical axis of the light source intersects with a longitudinal direction of the housing, and the imaging unit images a user's biometric feature irradiated with an irradiation light from the light source through the opening.
