The powering handle 5 for powering command is fixed to the powering handle rotation shaft 6, and both ends of the powering handle rotation shaft 6 are supported by powering handle rotation bearings 8a and 8b.

  A rotation-side rotation shaft 22 connected to the rotation side (rotation shaft) of the rotation-type angle detector 21 is supported by a rotation-type angle detector rotation bearing 23. A fixed side rotary shaft 24 connected to the fixed side (housing) of the rotary angle detector 21 so as to be concentric with the rotary side rotary shaft 22 is supported by a rotary angle detector rotary bearing 25.

  The brake handle rotation shaft 2 and the fixed-side rotation shaft 24 of the rotary angle detector 21 are coupled via the brake gear 3. The power running handle rotary shaft 6 and the rotary side rotary shaft 22 of the rotary angle detector 21 are coupled via a power running gear 7.

  The handle operation determination unit 28 determines whether or not the brake handle 1 is operated based on an operation signal from the sensor 27. When it is determined by the handle operation determination unit 28 that the brake handle 1 is operated, a signal indicating that is sent to a notch holding circuit 29 in the decoder unit 26.
