For example, Figure 1 (see Utility Model Application Publication No. 56-102210, etc.)
Those shown in are known. The structure of this strut-type suspension will be described. Reference numeral 1 denotes a vehicle body, and a rod 5 of a suspension strut is fixed to the vehicle body 1 via brackets 2, 3 and an elastic body 4. The rod 5 is connected to a piston that is slidably inserted into a strut outer cylinder (not shown), and the strut outer cylinder is connected to an arm that supports a wheel (not shown). An inner cylindrical metal fitting 8 is fixed to the aforementioned vehicle body 1 via a bracket 6 and a bearing 7, and a hole 9 formed in the inner cylindrical metal fitting 8 is inserted into the rod 5.
is slidably penetrated. Reference numeral 10 denotes an outer cylindrical metal fitting disposed radially outward of the inner cylindrical metal fitting 8, and this outer cylindrical metal fitting 10 includes a substantially cylindrical side wall portion 11 and a flange portion protruding from the upper end of the side wall portion 11 in the radial direction. 12. Side wall portion 1 of outer cylinder fitting 10
1 and the peripheral wall 13 of the inner cylindrical fitting 8 are connected by an elastic body 14 which has a substantially drum-shaped cross section and absorbs the load from the spring in the shearing direction. On the other hand, in order to increase the deformation tolerance of the elastic body 14, recesses are formed on the upper and lower surfaces thereof. Further, an elastic sheet 15 is attached to the lower surface of the flange portion 12. A metal fitting is also fixed to the strut outer cylinder (not shown), and a coil spring 16 is interposed between the flange portion 12 of the outer cylinder metal fitting 10 and the metal fitting fixed to the strut outer cylinder.

ルスプリング38が介装されている。 2 and 3 are diagrams showing one embodiment of the present invention. First, the configuration will be explained. 21 is a vehicle body;
A suspension strut rod 25 is fixed to the vehicle body 21 via brackets 22, 23 and an elastic body 24. The rod 25 is connected to a piston that is slidably inserted into a strut sleeve (not shown), and the strut sleeve is connected to an arm that supports a wheel (not shown). An inner cylindrical metal fitting 28 is fixed to the aforementioned vehicle body 21 via a bracket 26 and a bearing 27, and the rod 25 passes through a hole 29 formed in the inner cylindrical metal fitting 28 in a slidable manner. 30 is an outer cylindrical metal fitting arranged in the radial direction of the inner cylindrical metal fitting 28, and this outer cylindrical metal fitting 30 has a substantially cylindrical side wall portion 31.
and a flange portion 32 protruding from the upper end of the side wall portion 31 in the radial direction thereof. The side wall portion 31 of the outer cylindrical metal fitting 30 and the peripheral wall portion 33 of the inner cylindrical metal fitting 28 are connected by an elastic body 34 that has a substantially drum-shaped cross section and absorbs the load from the spring in the shear direction.
4 covers the upper surface 35 and lower surface 36 of the flange portion 32 as well as the upper surface 37 of the inner cylinder fitting 28. A metal fitting is also fixed to the aforementioned strut outer cylinder (not shown), and a coil spring 38 is interposed between the flange portion 32 of the outer cylinder metal fitting 30 and the metal fitting fixed to the strut outer cylinder.

8 and the outer cylindrical fitting 30 using the elastic body 34, the elastic body 34, which has been formed in a predetermined shape, is connected to the side wall portion 31 of the outer cylindrical fitting 30 and the inner cylindrical fitting 28.
The elastic body 34 covers the upper and lower surfaces 35 and 36 of the flange 32 and the upper surface 37 of the inner cylindrical fitting 28. Then,
The elastic body 34 is vulcanized and bonded to the outer cylindrical metal fitting 30 and the inner cylindrical metal fitting 28. In this way, since not only the upper surface 35 but also the lower surface 36 of the flange portion 32 is covered with the elastic body 34, it is not necessary to attach the sheet 15 to the lower surface of the flange portion 12 as in the conventional case, and the number of parts and manufacturing steps can be reduced. can be reduced.

衝撃を吸収することができる。 Next, when the vehicle runs in the rain, rainwater on the road surface is scattered by the tires and collects in the recessed portion of the upper surface of the elastic body 34. However, the elastic body 34
Since the upper surface 37 of the outer tube fitting 30 is covered, the side wall portion 31 of the outer tube fitting 30 and the peripheral wall portion 33 of the inner tube fitting 28 are not directly exposed to rainwater, and rust does not occur as in the conventional case. Therefore, the elastic body 34 that absorbs the load from the spring in the shear direction is the outer cylinder fitting 3.
0 and the inner cylindrical metal fitting 28, and the coil spring 38 does not fall off. Further, when a wheel rides on a convex portion while the vehicle is running, a large impact is applied to the strut outer cylinder through the wheel, and the outer cylinder metal fitting 30 may come into contact with the vehicle body 21. However, since the upper surface of the flange portion 32 of the outer cylinder fitting 30 is covered with the elastic body 34, the impact can be absorbed.

ングの脱落を防止できるという効果が得られる。 As explained above, according to the present invention, a strut type suspension is connected to an inner cylinder metal fitting connected to the vehicle body side, and an outer cylinder metal fitting disposed approximately concentrically with the inner cylinder metal fitting and supporting a spring connected to the wheel side. In a strut type suspension comprising a cylindrical metal fitting and an elastic body that connects the outer cylindrical metal fitting and the inner cylindrical metal fitting and absorbs the load from the spring in the shear direction, the upper surface of the outer cylindrical metal fitting and the inner cylindrical metal fitting are Since the upper surface is coated with the elastic body, rust can be prevented from forming on the outer and inner cylinder fittings, and the elastic body, which absorbs the load from the spring in the shear direction, can be prevented from peeling off from the outer and inner cylinder metal fittings. This has the effect of preventing the spring from falling off.
