In an electric linear motion actuator, while an axially forward load is not being applied to an object by an outer ring member, a preload is applied to a frictionally coupling surface by an elastic member, and, when the axially forward load is applied to the object by the outer ring member, an axial load applied to the frictionally coupling surface decreases by an amount equal to the axially rearward reaction force which the outer ring member receives from the object. The electric linear motion actuator includes a load sensor for supporting, through planetary rollers and a carrier, the axially rearward reaction force. The load sensor is arranged such that any change in magnitude of an axially forward load applied through a snap ring will not affect the value of the axially rearward reaction force detected by the load sensor.
