Abstract

A motor gear unit for a disc brake apparatus includes an electric motor, a speed reduction mechanism configured to transmit rotation of the electric motor to a plurality of rotary-to-linear motion conversion mechanisms arranged in a plurality of cylinders provided in a caliper, and a housing accommodating the electric motor and the speed reduction mechanism. The speed reduction mechanism includes a plurality of final gears connected directly or via another member to the plurality of rotary-to-linear motion conversion mechanisms and a power distribution mechanism that includes one support shaft and that is configured to distribute and transmit input power to the plurality of final gears. The power distribution mechanism is supported by the housing by supporting and fixing end portions of the support shaft on axially both sides to the housing.
