Ο ❹ : Horizontal, Ninja, respectively, is connected to the connector between the two bodies = two, • By connecting one end to the front body and the other end to the rear body ' The relative shake between the weakening effect. The damper is provided with a cylinder and a piston that protrudes freely from the gas red. The base end of the gas red and the protruding end of the piston rod are locked in the front body, and the other side is locked in the rear body. The eye member is fixed to the base end of the cylinder and the protruding end of the piston rod, respectively. The through shaft is fixed to the vehicle body through the bracket. The shaft is supported by the eye member for rotation on a straight axis and is capable of oscillating in a range along any vertical plane containing the vertical axis. Therefore, for example, the engaging portion of the shaft and the eye member forms a spherical surface, and a resin bush having a spherical sleeve is formed (formed as an outer circumference of the card 0 portion surrounding the spherical surface). The spherical bearing of the bushing and the eye member are ^ ^ k filled with grease. The sliding portion of the spherical portion of the weir member is provided with a dustproof member on the upper side and the lower side of the bushing to prevent water from penetrating into the sliding portion. The dust-proof members are respectively placed above and below to form an upward and downward concave portion of the eye member 200940387. SUMMARY OF THE INVENTION The eye member is directly exposed to wind and snow because it is disposed on the outer side of the vehicle body. Also, when ice or snow is removed from the vehicle body by the maintenance of the vehicle body, sometimes ice or snow flakes may fall on the eye member. As a result, the dust is disposed in the upward concave portion of the eye member, and is particularly susceptible to damage by ice or snow, and the snow and ice that is dropped by the maintenance of the vehicle body is also easily damaged. The damaged dust-proof member causes the water to penetrate into the gap between the shaft and the lining sleeve, and as a result, the grease leaking out of the sliding gap or the wear of the sliding portion becomes a bad cause. Accordingly, it is an object of the present invention to provide a dustproof member that covers the sliding gap of the jacket from snow or ice protection. In order to achieve the above (4), the eye member of the present invention is fixed to the end portion of the damper disposed in the horizontal direction, and the shaft having the spherical portion penetrates in the vertical direction, and is characterized in that: the bush member is provided to be slidably coupled to the spherical portion Spherical bearing; - for the dustproof member, for cutting off the spherical portion and the spherical bearing from the outside (four) portion, disposed above the bushing; and the snow removing member for covering the dustproof member above. The detailed and other features and advantages of the present invention are described in the description of the specification and are shown in the drawings. [Embodiment] Referring to Fig. 1, a double-tube type linear damper 1 is designed to reduce the relative sway between the bodies of the road vehicles, and to damper between the two sides of the connector between the vehicle bodies.

The inner side of the inner tube 3 is divided into two oil chambers 6 and 7 by a piston 4, 0, .sJ. The piston cup" oil to 6 passes through the extension side weakening valve 8 and communicates with the oil storage chamber 9 formed between the inner tube 3 and the outer door 2. The oil chamber 7 on the opposite side of the piston communicates with the oil reservoir 9 through the wish side relief valve 25. With the dust side weakening valve. The piston 4 is also provided with a side weakening 阙 ❹ 藉 By the above configuration, the linear damper 1 has the same weakening force for the expansion and contraction of the piston rod 5. The roll is not stretched and the eye member iQ is fixed to the base end of the outer tube 2. The eye member 11 is also fixed at the end.丞和< 犬出26 m:11 The sleeve that is fixed to cover the cylindrical shape of the piston rod 5 has a plurality of inner diameters larger than the outer diameter of the outer tube 2, as shown in the figure, on the outer side of the outer circumference 2 Tube _ part. Description I::::. Same as the structure of 11. In the following, the eye member 1 is used as an example of the shaft 5′′ 2A Xiao 2B, and the eye member 10 is inserted in the vertical direction through the metal at the intermediate value of the shaft 15 to form a spherical portion 15 . These bolts fix the shaft 15 to the bracket provided in the vehicle body. The eye member 10 is provided with a metal body 10A having a through hole. The liner u' is held by the metal holder 12 inside the perforation of the body ι. The bushing 13 is provided with a spherical bearing 1 on the inner circumference to support the sleeve 15 200940387 2 π 15A so as to be slidable. The rotation of the shaft 15 relative to the eye member 1Q with respect to the vertical axis by the spherical portion i5A and the spherical pumping action is shifted by I: a swing within a predetermined range of any vertical plane including the vertical axis; The annular recessed portion 16 formed in the spherical portion 15 and the sliding portion 15 of the bushing u and the core bushing 13 are immersed in the outer periphery of the drawing shape β 15A, and are pressed from below into the holder. The step is prevented by pressing the stopper 18 into the recess 17. The sliding portion of the spherical bearing that has fallen off the bushing 13 and the spherical portion of the shaft is interposed between the lubricating grease for lubrication. : A rubber dustproof member 〖9 is disposed inside the recessed portion 16. The dustproof member 19 is attached to the outer periphery of the outer periphery of the recess 15 so that the outer periphery abuts against the vertical wall surface of the recessed portion μ, and the dust is prevented from penetrating into the sliding side of the sliding portion 13 and the sliding portion of the spherical portion 15A of the shaft 15. Recognize. The same dustproof member 20 is disposed on the inner side of the stopper 18 of the recessed portion 17. ❹# The recessed portion of the upper dustproof member 19 is covered by the snow removing member: The snow removing member 21 is formed of a rubber plate and is attached to the outer circumference of the shaft 15. The snow removing material 21 is formed by the inner circumference of the 15C branch which is formed on the shaft 15. The snow removing member reaches the outer side of the recess 16 and overlaps the upper end surface of the holder. = the amount of overlap of the member U with the upper end surface of the holder 12 is set such that the snow removing member 21 can maintain the recessed portion 16 in the locked state in the range in which the shaft 15 is opposed to the eye member; Further, the snow removing member 21 is provided only above the dustproof member 上 on the upper side. There is no snow removal member for the dustproof member 2 below. The eye member 1 is further provided with a cover 22 other than the snow removing member 21. 8 200940387 The cover 22 is a lid member made of a metal material, and has a through hole 22A at the center of the shaft 15 at the center. The outer cover 22 is fixed to the body 1〇Α of the eye member by a plurality of screw inspections 23, To cover the snow removal components. A gap is provided between the sleeve 15 and the through hole 22'. This gap allows the shaft μ and the outer cover 22 to not interfere with each other within the range of the swing displacement of the shaft 15 with respect to the eye member 10. The other side: 'A gap is also provided between the outer periphery of the snow removing member 21 and the outer cover 22, and the gap is used to prevent the snow removing member 21 displaced in the horizontal direction from contacting within the swinging range of the shaft (9) ❹ the eye member ίο In order to allow the outer cover 22 to prevent the snow removing member 21 from being injured from the holder 2: the pressing force on the end surface floats & A n and ... sets the size of the outer cover 22 and the snow removing member 21 and the associated member, Passing between K | outside the week can ensure sufficient two. The inner peripheral portion and the snow removing member 21 are spaced apart from each other in the horizontal direction of the two vehicles W. Here, the eye member 1 is so that the dustproof member 19 is often exposed to the outside of the vehicle. Dust # ! ❹ or water seeps into the bushing i 3 fish # # # , There is dust prevention. = The function of the sliding part. However, the red is often exposed upwards, and the dustproof member 19 is maintained in the maintenance work of the vehicle body, and the ice and snow from the upper side are also dropped on the dustproof member 19, so that the dustproof member 2 scraps off dust or water, creates I, and the spherical shape. The sliding part of the part is infiltrated. ^The defect of the leakage of the grease or the wear of the sliding surface, etc. + the member 1G' is formed by the recess 16 which is covered by the dust member 19 (the recess 16 covered by the member 21 is removed* or the ice penetrates into the recess 16). Covering the outer part of the snow removal structure 21 by the outer cover 200940387 2, blocking the block snow or ice from reaching the '21° outer cover 22 and also achieving the suppression by the swinging of the car body in the row to make the snow removal The function of the member 21 floats. Therefore, regardless of whether the railway car is light, the middle and the parking can prevent the snow or ice from infiltrating the recess 16 of the dust-proof member 19, and the dustproof or waterproofing of the dust-proof member 19 is maintained for a long time. ^ 'It is also possible to prevent the line of the upper dust-proof member 19 from deteriorating.
