As a result, the compression deformation of the entire coil spring 26 is stabilized.
- the coil spring 26 is compressed, and the small pitch portions 26B and 26C that are compressed subsequent to the large pitch portion 26A are compressed leaving the pushing amount for unlocking the rod 20 (S5-S4).
- the lock mechanism locks the rod 20 at the retracted position of the case 16. For this reason, the urging force of the coil spring 26 in the locked state in which the rod 20 is locked to the retracted position of the case 16 is increased, and flapping of the rod 20 and the fuel lid 12 in the locked state can be suppressed.
- the end 108A of the control spring 108 is locked and locked by the recess 106A of the cam 106, and the rod 102 is pushed into the case 100 again, so that the end 108A of the control spring 108 is disengaged from the recess 106A of the control cam 106.
- a biasing mechanism that biases the rod 102 in a direction protruding from the case 100 using a so-called heart cam type lifting device (a lifting device described in German Patent No. 19655944 A1 etc.) released from the locked state. It is good also as a structure using the coil spring 26 of 1 embodiment.
- the thickness of the small pitch portions 26B and 26C of the coil spring 26 is made larger than the thickness of the large pitch portion 26A, or the coil spring 26
- the increase rate of the urging force with respect to the initial stroke of pushing the rod into the case by making the elastic force of the material constituting the small pitch portions 26B and 26C of the 26 stronger than the elastic force of the material constituting the large pitch portion 26A
- the coil spring 26 is used as the urging mechanism.
- the increasing rate of the urging force with respect to the initial stroke for pushing the rod into the case follows the initial stroke.
- Another urging mechanism in which columnar rubbers having different elastic forces are connected may be used so that the rate of increase of the urging force with respect to the later stroke becomes smaller.

Abstract
Description
次に、本発明の押上装置の第1実施形態を図1~図23に従って説明する。
図4に示すように、本実施形態の押上装置10は、フューエルリッド12に対向する車体としての、例えば、インナーパネル14(車体)に設けられており、インナーパネル14に開閉可能に取り付けられたフューエルリッド12が、押上装置10によって、開方向(図4の矢印A方向)へ押し出されるようになっている。
図5に示すように、ケース16は筒形に形成されている。また、インナーパネル14には、表裏面に貫通する方形の取付孔32が形成されており、この取付孔32にケース16が固定されている。
図1に示すように、キャップ18は、ケース16の開口上面に取り付けられている。
図1に示すように、ロッド20は、ケース16内にスライド可能に保持され、ケース16内から突出してフューエルリッド12を押し出すようになっている。
図22及び図23に示すように、スリーブ24は、スリーブ本体88、張出部84、縮径部78及びスリット92を備えている。
図1に示すように、コイルスプリング26は、ケース16とロッド20との間に位置し、ロッド20の下側ロッド部68に回転子22及びスリーブ24を挿通した状態で、スリーブ24の張出部84とケース16の底との間で圧縮されるようになっており、ロッド20をケース16内から突出する方向に向かって付勢している。また、コイルスプリング26は、ケース16内で弾縮され、回転子22をロッド20のカム部64に向かって付勢している。
図6に示すように、ロック機構は回転子22を備えた回転カム式となっており、ケース16とロッド20との間に位置し、コイルスプリング26の付勢力に抗してロッド20をケース16の後退位置にロックするようになっている。また、回転子22は、ロッド20の下側ロッド部68に回転可能で、且つ軸方向にスライド可能に支持されており、カム部64の固定側カム72にかみ合うと共に、ロッド20のスライドにより係脱し、一方向の回転力を付与するための可動側カム部82を有している。
図1に示すように、ブーツ28は、ケース16から突出する上側ロッド部66を覆う伸縮可能なものであり、ケース16に取り付けられている。ブーツ28は下面が開口した中空の蛇腹状に形成されており、上端部が袋状に閉じている。ブーツ28の上端部の内周面には、半径方向に内向きに環状に突出した環状突起94が形成されており、環状突起94はロッド20の環状溝76にはまり込むようになっている。また、ブーツ28の開口下面の内周面には、半径方向に内向きに環状に突出した環状凸部96が形成されており、環状凸部96は、ケース16の取付凹部36にはめ込まれている。
次に、本実施形態の押上装置10の作用効果について説明する。
図4に示すように、押上装置10は、組み立てた状態で、ケース16を、インナーパネル14の取付孔32に合わせてはめ込むことで、インナーパネル14に固定される。また、図10に示すように、フューエルリッド12が閉じた状態では、押上装置10はロッド20が短縮したロック状態にロックされている。
以上に於いては、本発明を特定の実施形態について詳細に説明したが、本発明は上記実施形態に限定されるものではなく、本発明の範囲内にて他の種々の実施形態が可能であることは当業者にとって明らかである。例えば、図24に示す第2実施形態の押上装置90のように、ケース100にロッド102が押し込まれることによって、制御スプリング108の端部108Aがハート形状の制御カム106に沿って移動し、制御カム106の凹部106Aで制御スプリング108の端部108Aが係止されロック状態となり、再度、ケース100にロッド102が押し込まれることによって、制御スプリング108の端部108Aが制御カム106の凹部106Aから外れてロック状態が解除される、所謂、ハートカム式押上装置(独国特許19650594A1号等に記載の押上装置)を使用し、ロッド102をケース100内から突出する方向へ付勢する付勢機構として第1実施形態のコイルスプリング26を使用した構成としてもよい。
