PROBLEM TO BE SOLVED: To improve workability in assembling by preassembling pushers, displacement sensors, etc., as a sensor assembly thereby reducing the number of parts. SOLUTION: The sensor assembly 21 comprising cylindrical cases 22, bushing 23, the pushers 24, springs 29, the displacement sensors 30, etc., is preliminarily made a unit to be assembled. When the sensor assembly 21 is attached to a lever support body 12, the bushing 23 of each sensor assembly 21 is respectively fitted into a hole 14B with step of a head easing 14, a fixing plate 18 is mounted on the head easing 14 on the bushing 23, and the fixing plate 18 is also fixed onto the head easing 14 by using bolts or the like. Thus, respective sensor assemblies 21 can be collectively fixed to the head casing 14 to simplify assembling work of the control lever unit.
