都合を伴う。Conventionally, this type of device consists of a main pipe having an internal bottom pipe that is fitted with a piston at the lower end of a piston rod, and upper and lower halves having an intermediate connection part that is fitted and connected to each other. Also has an oil seal around its outer circumference.
A type in which an outer cylinder is provided through a member is known, but in this case, the main pipe is as shown by a in Fig. 1, for example, and the upper pipe member is relatively thin, and The general method is to press-fit the lower cap member C and connect them together by seam welding, thus obtaining the intermediate connection part d at a relatively lower position. In order to prevent oil leakage from the connection part d, precision is required for welding, and it is necessary to increase the rigidity of the member, which is disadvantageous in that machining is troublesome.

部材に対しその上方位置とすることを特徴とする。The object of the present invention is to obtain a device free from such inconveniences, in which a main pipe having an internal bottom pipe that is fitted with a reston at the lower end of a piston rod is fitted and connected to each other. In the case of a type that is composed of upper and lower halves having an intermediate connecting part and having an outer cylinder on the outer periphery of the upper and lower halves with an oil seal member interposed therebetween, it is preferable that the connecting part is located above the seal member.

3) and the vehicle body frame (4) above it. As clearly shown in FIG. 3, the main body il+ has a main pipe (8) having an internal bottom pipe (7) fitted with a piston (6) at the lower end of the piston rond (5), and a connecting part (9) in the middle. ), and is equipped with an outer cylinder 03I on its outer periphery via an A-il seal member Q2+, which is particularly different from the conventional one in this point (10). 141 is a damper rubber in the middle of the piston rond (5), 051 is a pan bust collar that supports this from the back, αe is a coil spring on its outer periphery,
a7) represents a dust boot extending downward from the outer cylinder (131), and α~ represents a part of the communication port that communicates the inside of the main pipe (8) with the internal space Q1 of the outer cylinder 0~.

した。More specifically, as shown in FIG. 4, the main pipe (8) has relatively thin upper and lower halves QOI00 that are loosely fitted into each other and plasma welded to form a relatively thin connection part (9). For example, as clearly shown in FIG. 6, the seal member QOI is positioned above the seal member QOI on its outer periphery.

不要となる。Here, the oil in the main pipe (8) can freely flow into the inner space H of the outer cylinder from the communication port α frame at the top thereof, and the sealing member prevents the oil that has flowed in from leaking out. are doing. Therefore, above the seal member (101) there is a joint (
