In addition, the present invention relates to an oil supply device of an automobile shock absorbing means for opening and closing a vehicle to prevent noise generated by the action of the shock absorbing means.
    The damper, which is a shock absorbing means of a switch, such as a tailgate installed at the trunk of a vehicle, plays a role of catching vibration of the switch during driving by sliding friction during opening and closing operation of a closed body.
    A damper as an impact mitigating means will be described in more detail with reference to FIG.
    1 is a cross-sectional view of a main part of a tailgate of a minivan vehicle such as Starex, and showing a damper portion in a closed state of the tailgate.
    As shown in the drawing, the conventional tailgate damper includes a female damper 3 supported by a spring 2 on the vehicle body 1 and a water damper 5 attached to and fixed to the tailgate 4.
    The female damper 3 and the male damper 5 are formed to face opposite slopes. When the tail gate 4 is opened, the inclined surfaces of the male dampers 5 slide along the inclined surfaces of the fixed female dampers 3. You will get away.

Since the friction force with the surface of the vehicle body 1 is generated due to the movement in the guided state, the retraction movement operation is not smooth, and the arm damper according to the vibration of the vehicle when the tail gate 4 is driven in the closed state. (3) also causes a friction with the vehicle body (1) surface while vibrating has a problem that generates noise.
    In other words, the noise of 'slip off' is generated at the sliding part between the body 1 surface and the arm damper 3 surface, which stimulates the driver's nerves, and when the friction is intensified, the damper is worn out and shortens its life. You will have problems such as
    In order to solve such a problem, conventionally, grease such as grease is applied between the arm damper 3 and the vehicle body 1 surface, but grease does not penetrate smoothly into the frictional surface in close contact, and there is a need for frequent application. I had another problem.
    The present invention has been made to solve the conventional problems as described above, the object of the present invention is to supply the appropriate amount of oil, such as grease to the impact mitigating means in accordance with the opening and closing operation of the opening and closing the smooth operation of the impact mitigating means is The present invention provides an oil supply device for an automobile shock absorber for opening and closing the vehicle so as to prevent noise from occurring due to the action of the shock absorber.
