一体回転可能に固定し、該両ギアに噛合する第３
、第４ギアを前記本体に固定された回転抵抗を有
する緩衝軸に同軸で固定し、前記第１、第３ギア
は前記リツドの開閉範囲全域で互いに噛合するよ
う歯を設け、前記第２、第４ギアはリツドの開閉
範囲の中間部で噛合しないよう一部除いて歯を設
けたリツド開閉機構の緩衝装置において、 前記第２ギアを軸方向に変位可能とすると共に
、前記第４ギアとの噛合を解除する方向へ付勢し
、該第２ギアの付勢方向側の面に円周方向に沿つ
てカム溝を設け、前記本体に前記カム溝の底面に
当接して前記第２ギアの軸方向の変位を制限する
ピンを設け、前記カム溝の底面に、前記第２、第
４ギアが少なくともリツドの開成動作時の完閉付
近で噛合しないよう傾斜及び段差を設けたことを
特徴とするリツド開閉機構の緩衝装置。[Claims for Utility Model Registration] First and second gears having different diameters are fixed to a lid attached to the main body via a rotation shaft so as to be able to rotate together coaxially with the rotation shaft, and are engaged with both gears. 3rd to do
, a fourth gear is coaxially fixed to a buffer shaft having rotational resistance fixed to the main body, the first and third gears are provided with teeth so as to mesh with each other over the entire opening/closing range of the lid, In a shock absorbing device for a lid opening/closing mechanism, the fourth gear is displaceable in the axial direction in a shock absorbing device for a lid opening/closing mechanism in which teeth are provided except for a portion of the lid so as not to engage with each other in the middle of the opening/closing range of the lid. A cam groove is provided along the circumferential direction on the surface of the second gear in the biasing direction, and the second gear is pressed in a direction in which the second gear is disengaged from the second gear. A pin is provided to limit displacement in the axial direction of the cam groove, and a slope and a step are provided on the bottom surface of the cam groove so that the second and fourth gears do not engage at least near the fully closed position during the opening operation of the lid. A shock absorber for the lid opening/closing mechanism.
