FIG. 1 relates to an embodiment of a bush made of an elastic body of a motor, in which a bush made of an elastic body 6 is attached to a wall portion of the motor. FIG. 2 is a view showing a sectional view of a bush made of an elastic body 6, 2 is a hollow conical surface provided in the lead wire fitting portion 1 of the bush made of the elastic body 6, 3
Indicates a hollow cylindrical surface. The shape of the hollow conical surface 2 provided in the lead wire fitting portion 1 is such that the diameter of the lead wire insertion port 4 is equal to the lead wire diameter and is inclined by 10 to 25 °, and the hollow cylindrical surface 3 is formed.
It has a shape that gradually becomes thinner up to the diameter of. The diameter of the hollow cylindrical surface 3 is 70 to 80% of the diameter of the lead wire 5, and the lead wire is formed by the interference between the outer diameter of the lead wire 5 and the diameter of the hollow cylindrical surface 3. Adheres to 5 for waterproofing. Since the hollow conical surface 2 has a smaller interference compared to the hollow cylindrical surface 3, if the length of the hollow cylindrical surface 3 is short, the hollow cylindrical surface 3 is distorted and a gap is formed when the lead wire 5 is pulled laterally. So it will not be sealed. Therefore, the ratio of the lengths of the hollow conical surface 2 and the hollow cylindrical surface 3 is set to 1: 2 so that no gap is left even if the lead wire 5 is pulled laterally. FIG. 3 shows a cross-sectional view in which the lead wire 5 is inserted into the bush made of the elastic body 6. When the lead wire 5 is inserted into the bush made of the elastic body 6, the force of F acts and the hollow conical surface 2 divides the force into F1 and F2. F1 is a force and a direction that works perpendicularly to the hollow conical surface 2 and pushes the hollow conical surface 2 apart. And direction. Thus, when the lead wire 5 is inserted, the force of F1 works and the tip of the lead wire 5 spreads out the hollow conical surface 2, and at the same time, the inlet diameter of the hollow cylindrical surface 3 also expands and the force of F2 causes the lead wire 5 to move. enter. The hollow cylindrical surface 3 is shorter than the entire height of the bush made of the elastic body 6 and has less friction than the total height of the normal lead wire fitting portion 1 is equal to the total height of the bush made of the elastic body 6, so that the lead wire 5 can be easily passed. You can
Further, when the hollow conical surface 2 has a large inclination, F1 is oriented in substantially the same direction as F. In this case, the 4-lead wire insertion port cannot be opened and the lead wire 5 is difficult to pass through. On the contrary, if the lead wire 5 is small, the length of the hollow cylindrical surface 3 becomes short, so that when the lead wire 5 is pulled laterally, a gap is formed and sealing is not performed. FIG. 4 is a cross-sectional view showing the lead wire 5 passed through the bush made of the elastic body 6. By passing the lead wire 5 through the lead wire fitting portion, the bush made of the elastic body 6 is changed from the shape shown by the broken line. Distort in the direction of the arrow. The hollow cylindrical surface 3 has a diameter of 7
Since the diameter is 0 to 80%, a force acts in the direction in which the lead wire 5 is tightened, and the lead wire 5 is in close contact. Since the inlet of the lead wire fitting portion 1 of the hollow conical surface 2 is the same as the lead wire 5, the tightening margin gradually increases as it goes deeper, and the bushing made of the elastic body 6 forms a bush. The bush made of the elastic body 6 is pushed by the wall portion and the X portion is a fulcrum, and the bush made of the elastic body 6 is distorted in the vertical direction and further comes into close contact with the lead wire 5.
