Title:
ELECTRIC LINEAR MOTION ACTUATOR AND ELECTRIC BRAKE DEVICE
Document Type and Number:
Japanese Patent JP2011241851
Kind Code:
A
Abstract:
To provide an electric brake device having an electric linear motion actuator assembled therein, which provides a desired braking force with high accuracy.
A load sensor 30 for detecting a pressing force of an outer ring member 5 linearly driving a driving object is provided inside a motion conversion mechanism which converts a rotational motion of a rotary shaft 4 transmitted from an electric motor 2, into a linear motion of an outer ring member 5 serving as an output member. Thereby, when the load sensor is used in the electric brake, a braking force generated by the braking object of the braking device is directly detected, so that a desired braking force is provided with high accuracy.
