A device generating a single-line diagram of each power system by diverting a part of a configuration common to the power systems is provided when a plurality of power systems having similar configurations exist. The device includes an input portion, a controller, and a storage. The input portion receives first setting related to a first power system, second setting related to a second power system, and third setting common to the first and second power systems. The controller generates setting data of a first single-line diagram including the first setting and the third setting, generates setting data of a second single-line diagram including the second setting and the third setting, and stores the setting data of the first single-line diagram and the setting data of the second single-line diagram in the storage.

Device, method, and non-transitory computer-readable medium for preparing single-line diagram

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.
