として使用する場合にリザーブタンクの取付の手間が不
要であるという事から、リザーブタンクはシリンダの端
部金具と一体に形成される。This small-sized, pressure-relaxing device can be used for 1 to 1 cylinder.
? The reserve tank is formed integrally with the end fitting of the cylinder because the amount of oil released is relatively small and there is no need to install a reserve tank when used as a shock absorber. .
その結果端部金具形状がａ雑となるため、アルミニウム
合金で鋳造により製造されている。As a result, the shape of the end fittings becomes rough, so they are manufactured by casting from an aluminum alloy.

ザーブタンクの取付の手間が不要である利点を保持しつ
つ生産能率の向上を図らんとするものである。This entire project was designed in consideration of these points, and is intended to improve production efficiency while maintaining the advantage of not requiring the effort of installing a reserve tank.
この目的はそれぞれ別体に形成したシリンダとリザーブ

問題を回避して生産能率がよく、リザーブタンクの取付
手間の不要な緩衝器を堤イ共するものである。The purpose of this is to connect the cylinder and the reserve tank, which are formed separately, through an oil pipe with an oil passage formed separately, and to hold the reserve tank by this oil pipe, thereby avoiding the problem of core sand mentioned above and improving production efficiency. A shock absorber that eliminates the need to install a reserve tank is also included.
以下にこの発明を自動、２輪車の後輪懸架装置直におけ

積に見合うようにシリンダ５１内の油量の調整を行う。50 is a shock absorber mounted between the vehicle body 20 and the rear arm 30. The buffer 50 is configured as shown in FIG.
It includes a cylinder 51, a piston 52, and a rod 53 that supports them. 54 is a reserve tank, 55
C. An oil pipe with an oil passage formed on its inner surface. The inside of the cylinder 51 is filled with oil, and the piston 52 is provided with an orifice (not shown), and as the rod 53 moves in and out of the cylinder 51, the oil flows through this orifice to generate a damping force. The reserve tank 54 adjusts the amount of oil in the cylinder 51 to match the volume of the rod 53 entering the cylinder.

は偏平に成形されている。Oil is stored in this reserve tank 54 up to the position of line 0 in the figure, and high-pressure nitrogen gas is stored above the oil level. As described above, the oil pipe 55 communicates the oil phase of the syringe 51 and the reserve tank 54 and is made of a drawn steel pipe, and as shown in FIG. 3, the middle portion excluding both ends is formed flat.
