欠点を生じている。 Conventionally, sealing devices for bearings to prevent muddy water, dust, etc. from entering the bearings of motorcycles have been developed by machining and forming a locking part on the inner wall near the end face of the bearing. A sealing material such as rubber is attached to the end surface so as to be secured thereto. Therefore, a locking portion must be formed on the bearing portion, resulting in an increase in manufacturing steps.

装置を提供することにある。 The purpose of this invention is to have a simple structure, easy installation, and to be able to reliably prevent water, dust, etc. from entering the bearing, and to have a large effect in preventing mud from adhering to the bearing. An object of the present invention is to provide a sealing device for a bearing.

中に跳ね上げた泥の影響をなくすことができる。 An embodiment of the present invention will be described below with reference to the drawings. A motorcycle frame 1 has a seat 2, a rear fender 3, etc. mounted on its upper part. Further, a swing arm 5 is swingably attached to the lower part of the frame 1 via a pivot shaft 4, and a rear tire 6 is rotatably attached to the end of the swing arm 5. On the other hand, a bearing part 7 is attached to the middle part of the frame 1, and this bearing part 7 is for rotatably supporting a lever 8 that constitutes a part of the rear suspension. That is, the lever 8 has one end rotatably connected to the swing arm 5 via a link 9, and the other end of the lever 8 is connected to the pivot shaft 4 via a rear suspension unit 10. .
Reference numeral 11 indicates a frame cover of a motorcycle, and a non-water-absorbing elastic body 12 such as urethane foam is connected and fixed at a suitable location on the inner side 11a of the frame cover 11. This will be explained in detail with reference to FIG. 3, which is an enlarged view of the main part of FIG. A seal 14 and a bearing 15 are provided. The shaft portion 7a has a small diameter inside the bearing portion 7, and the bearing portion 7 is fixed with a nut 16 screwed into a male threaded portion 7b at the tip thereof. The non-water-absorbing elastic body 12 is adhered to the inside of the frame cover 11 with one side pressed against the protrusion 7c provided on the outer periphery of the bearing portion 7 and the tip of the male threaded portion 7b. This makes it possible to prevent water, dust, etc. from entering the bearing portion 7 when the motorcycle is running, and also eliminates the influence of mud thrown up while the motorcycle is running, as will be explained next.
オートバイが走行するとき、水やほこり、ある

しかしながら本考案では非吸水性弾性体１２が軸
受部７に圧接しているので、このようなことはな
い。なお、反対側はオイルシール１４とワツシヤ
１３により、、水、ほこりの侵入を防止すること
ができる。 Suppose that water, dust, or mud gets inside the frame cover 11 when the motorcycle is running. It is of course undesirable for water or dust to adhere to the bearing portion 7 on the inside of the frame cover 11, but mud can have a particularly bad effect. In other words, if the non-water-absorbing elastic body 12 according to the present invention is not present, the part surrounded by the protrusion 7c of the bearing part 7 (the outer periphery of the nut 16) will accumulate mud that has been thrown up, and it will not be necessary to disassemble it for maintenance. When attaching and detaching the nut 16, it becomes difficult to apply a wrench to the nut 16, or sand gets stuck in the male threaded portion 7b, causing the screw thread to become crushed or unable to turn.
However, in the present invention, since the non-water-absorbing elastic body 12 is in pressure contact with the bearing portion 7, such a problem does not occur. The oil seal 14 and washer 13 on the opposite side can prevent water and dust from entering.
以上、説明したように、本考案のシール装置に
よれば、軸受部の内壁加工の必要性がないから製
作が容易であり、更に、シール部の構成が簡単に
なると共に、取付が極めて容易になるという効果
を生ずる。 As explained above, according to the sealing device of the present invention, manufacturing is easy because there is no need to process the inner wall of the bearing part, and furthermore, the structure of the sealing part is simple and installation is extremely easy. It produces the effect of becoming.
