とを目指している。2. Description of the Related Art When getting in and out of an automobile in winter, it is often experienced to receive an electrostatic shock when touching a door. In addition, in high-rise apartments and the like, when moving in and out of laundry from the balcony to and from the room, and when taking in dried futon, you often suffer from electrostatic shock when you touch the door. As means for preventing these, in automobiles, methods such as discharging from the vehicle body to the air or discharging by dropping a conductive material from the vehicle body to the road have been adopted. In addition, there is a small device that discharges static electricity from the human body to the air by gripping it with a key holder-shaped plastic product, but in order to reduce the electrostatic shock to the extent that no discomfort remains, hold it for a long time in your hand. Need to be. In these methods, the static electricity accumulated in the human body or the target object is discharged into the air, and when a person touches the target object,
We aim to realize a state in which the charge accumulated in both is significantly reduced.

ックを受ける可能性がある。Therefore, in the prior art, even if the target object is prevented from being charged, static electricity may be shocked if static electricity is accumulated in the human body, and conversely, even if static electricity is discharged from the human body into the air. If an object is charged, it may receive an electrostatic shock.

ショック防止装置の提供を目的とするものである。Generally, when a large potential difference exists between a target object, for example, a handle of a metal door and a human body, an electrostatic shock eliminates the potential difference at the moment of contact with the target object. In addition, the amount of electricity is very small, but a large peak value of the current flows. In order to reduce the electric shock to an unnoticeable level, it is necessary to reduce the current peak value and further reduce the product of voltage drop and current at the fingertip touching the metal door, for example. It is an object of the present invention to provide an electrostatic shock preventive device which slowly makes a target object and a human body temporally but equipotentially in a sense of daily life and consumes most of electric energy therein. It is a thing.

ように働く。When the human body is considered as a capacitor for storing static electricity, it is expected that the peak current value will be remarkably reduced if the discharge between the human body and the target object is performed through electric resistance. In addition, if a large electric resistance is used during discharge, this electric resistance bears most of the voltage drop. Both mechanisms work to reduce electrostatic shock.

The part 1 is brought into contact with the target object, and is quickly discharged so as to equalize different electrostatic potentials between the human body and the target object. If the human body is a capacitor of capacity C for storing electricity and the resistance value of the device according to the present invention is R, the time constant of the discharge of static electricity is the product of C and R. Therefore, when directly touching the target object made of metal, the resistance value between the fingertips of the hand and the target object is almost zero, so that a large current is instantaneously generated and an electrostatic shock is felt. CR when touched through
The current gradually flows during the second, and the peak value of the current is greatly reduced, so that electrostatic shock can be prevented. Further, in this case, most of the electric energy is consumed in the resistor, and the electric energy consumed at the fingertip is reduced. With the above two mechanisms, it is possible to prevent electrostatic shock during discharge,
Moreover, even if the target object is directly touched thereafter, it is not subjected to electrostatic shock. .
