To provide a control device of an elevator, accurately obtaining the time to correct a car load signal and a correction amount for the car load signal to achieve accurate balance torque output.
A traveling loss torque current calculating device 21A calculates a travel loss torque current, which is a difference of a balance torque current command value at the traveling start to a q-axis torque current command value in traveling at the highest speed. When the traveling of a car 2 ends, a comparison and determination device 22 corrects an offset value of a load signal based on an offset correction value computed by a correction value computing device 32 based on a difference of a traveling loss torque current in traveling at the highest speed to a traveling loss torque current in adjusting an offset value of a load signal when an absolute value of a difference of a traveling loss torque current in traveling at the highest speed to a traveling loss torque current output in adjusting the offset value of the load signal is a predetermined load signal correction determination value or more.
