An electric linear motion actuator is provided which includes an outer ring member, a rotary shaft, planetary rollers, and a carrier including a disk, and in which the outer ring member is formed with a helical rib, each of the planetary rollers being formed with circumferential grooves in which the helical rib is engaged. When the rotary shaft rotates, the planetary rollers rotate about their axes while revolving around the rotary shaft so that the outer ring member axially linearly moves. The actuator includes thrust roller and retainer assemblies each mounted between one of the planetary roller and the disk of the carrier, and each guided by a raceway, i.e., an end surface of the corresponding planetary roller. The actuator includes a common raceway disk common to all of the thrust roller and retainer assemblies, and mounted between the thrust roller and retainer assemblies and the disk of the carrier.
