Through this, it is screwed into a fixing screw hole 12 formed in the flat surface 11 of the hemispherical body of the handle body 1. In this case, the handle body 1 and the handle base 4 are integrally fixed to each other by the assembling screw 5, but the contact plate 2 is
There is a small clearance between both the handle base portion 4 and the handle base portion 4 so that the handle base portion 4 is not sandwiched between them and is in a floating state. That is, the contact plate 2 has a clearance between both the handle body 1 and the handle base 4, and the assembling screw 5 is inserted into the arc slit 25 and has a degree of freedom in the circumferential direction.

The rectified output voltage _VDC of the rectifier circuit R is applied to one input terminal of the voltage comparator C. A comparison voltage _vRF is applied to the other input terminal of the voltage comparator C. Voltage comparator C, in the steady-state, keep the design of outputting the H logic signal to the output terminal O _UT. r is the equivalent resistance of the human body. When the operator's hand contacts the contact plate 2 by operating the handle, the equivalent resistance r of the human body is connected between the contact plate 2 and the ground. Due to this contact, the rectified output voltage v _DC decreases as compared with the comparison voltage v _RF, and the H logic signal is inverted to L. This inversion is output via the output terminal O _UT. This output signal is used as a contact detection signal indicating that the operator's hand has contacted the steering wheel.

Another conventional example will be described with reference to FIG. FIG. 7A is a diagram showing the handlebar viewed from the side, and FIG. 7B is a diagram showing the handlebar viewed from the front.

A contact detection circuit incorporating the above-described contact plate 2 and ground plate 7 will be described with reference to FIG. 8 omits parts common to the contact detection circuit of FIG. 6 and shows only necessary parts. In FIG. 8, the contact plate 2 is connected to one end of the sensitivity setting resistor r _S of the sensitivity setting section S. Ground plate 7
Is connected to a ground terminal which is the other end of the sensitivity setting resistor r _S. Here, when the operator's hand touches both the contact plate 2 and the contact plate 2 by operating the handle, the equivalent resistance r of the human body is generated between the contact plate 2 and the contact plate 2.
Is connected, and the sensitivity setting resistance r _S is short-circuited by the equivalent resistance r of the human body. The resistance value of the sensitivity setting resistor r _S decreases as compared with a state in which the equivalent resistance r is not short-circuited by the short circuit. Due to the decrease of the resistance value, as in the conventional example, H logic signal at the output terminal O _UT is inverted L, and the contact detection signal is generated indicating that the operator's hand in contact with the handle.
