用意している。2. Description of the Related Art As a bearing device, for example, the one shown in FIG. 3 has been known. FIG. 3 is a longitudinal sectional view showing a bearing portion of the power tool. Reference numeral 1 denotes a bearing housing. The bearing housing 1 is provided with a circular recess 2 from one side, and a small circular recess 3 is provided at the back of the recess 2. (It is usual to provide various parts in the recess 2, but this point is not shown.) Then, on the side opposite to the side where the recess 3 is provided, a small circular through hole is formed concentrically with the recess 3. 4 is open. A sealing plate 5, a washer 6 and a bearing 7 having a size just fitted into the recess 3 are prepared, and the sealing plate 5 and the washer 6 are provided.
-The bearings 7 are fitted in the recesses 3 in the order.
The sealing plate 5 is used for dust prevention, and is usually made of thin and soft paper.
The bearing 7 is a well-known one, in which a ball or a roller is fitted between the outer ring 8 and the inner ring 9. The diameter of the through hole 4 is smaller than the inner diameter of the outer ring 8 of the bearing 7. Further, a pin 10 is attached to the rear surface of the bearing housing 1. Then, a tool 11 having an outer diameter of the tip portion which is just large enough to fit into the through hole 4 is prepared.

できないこととなってしまった。In the above-described bearing device, the tip of the tool 11 is used when the bearing 7 is out of order for replacement when the bearing 7 is out of order or when the normal bearing 7 is taken out for re-use because the other part is out of order. Into the through hole 4 to push the bearing 7. At this time, the through hole 4 and the tool 1
Since the tip of 1 is small, the pushing force of the tip of the tool 11 tends to concentrate on the inner ring 9 of the bearing 7 via the seal plate 5 and the washer 6. Therefore, there is no problem if the entire bearing 7 can be pushed out in its entirety. However, the outer ring 8 fits exactly into the recess 3, and a strong frictional force is generated between the outer periphery of the outer ring 8 and the bearing housing 1.
For this reason, the thin and soft seal plate 5 may be broken, and the inner ring 9 may be pushed out while leaving the outer ring 8 in the recess 3. If the outer ring 8 remains, the only option is to find a suitable tool or the like, insert the tip of the tool or the like into the recess 3, take the time to take it out while trying again many times. The struggle was usually hard. Further, when trying to take out a normal bearing 7, the bearing 7 is damaged and cannot be reused.

ができる工具を提供する点にある。[0004] Or, when the bearing 7 is pushed out by the tool 11, the bearing 7 cannot be pushed straight, and may be pushed obliquely. When a force in an oblique direction is applied, the outer ring 8 tilts and is caught in the recess 3, and it is finally difficult to remove the outer ring. Due to the excessive force applied, the bearing housing 1 may be damaged in some cases, making it more difficult to remove it. If the bearing housing 1 is damaged, it may become unusable and must be replaced. If the through hole 4 is large, the entire bearing 7 can be pushed out smoothly by pushing the entire bearing 7 with the tool 11 having a large tip. However, if the through hole 4 is too large, the entire bearing 7 or the inner ring 9 may jump out into the through hole 4 during use. Or
Since various components such as the pins 10 are provided in the bearing housing 1, the large through holes 4 may not be formed in some cases.
Therefore, the through hole 4 cannot usually be enlarged. A problem to be solved by the present invention is to provide a bearing device and a bearing device which can extrude the bearing 7 fitted in the recess 3 of the bearing housing 1 very easily without deteriorating the fitted state of the bearing 7. It is an object of the present invention to provide a tool that can easily push out a bearing from the bearing device.

こともある。SUMMARY OF THE INVENTION A bearing device according to the present invention and a tool for pushing out a bearing from the bearing device solve the above problems and are as follows. That is, the recess 3 having the same diameter as the bearing 7 to be fitted is provided inside the bearing housing 1 from the inside,
This is a bearing device in which a bearing 7 is fitted in the recess 3, and two slits 12 penetrating from the outer surface of the bearing housing 1 to the recess 3 are provided outside the recess 3. In addition, the shape and size of each of the slits 12 just fit into the slits 12, and the indentations 3 from the outer surface of the bearing housing 1.
This is a tool having a tip portion having a length capable of being inserted into the inside and pushing out the bearing 7 in the recess 3. The two slits 12 are desirably provided in a cross shape at right angles, but may be provided so as to intersect in an X shape. It is desirable that both slits 12 be at least as long as each end reaches the outer ring 8 of the bearing 7 housed in the recess 3. As will be described later as an example,
In the case where the seal plate 5 or the washer 6 is fitted therein, even if the length does not reach the outer ring 8, it may be OK.

FIG. 1 is a longitudinal sectional view showing the embodiment, and FIG. 2 is an AA view of FIG. A recess 2 and a recess 3 are provided in the bearing housing 1, and a seal plate 5 and a washer 6 are provided in the recess 3.
-Up to the point where the bearing 7 is fitted, it is the same as the conventional one, but the through hole part is different. That is, instead of the round through hole 4, two slits 12 penetrating from the outer surface of the housing 1 to the recess 3 are provided in a cross shape, and both slits 12 have a length such that both ends reach the outer ring 8 of the bearing 7. ing. Then, a tool 13 having a tip having a shape and a size that exactly fits in the two slits 12 and having a length capable of being inserted into the recess 3 from the outer surface of the bearing housing 1 and pushing out the bearing 7 in the recess 3 is prepared. doing. When taking out the bearing 7 fitted in the recess 3 of the bearing housing 1, the bearing housing 1
The tip of the tool 13 is inserted into the two slits 12 from the outside, and the bearing 7 is pushed forward through the seal plate 5 and the washer 6. The tool 13 pushes the bearing 7 while applying an equal force to the outer ring 8 and the inner ring 9. Therefore, there is no case where only the inner ring 9 is pushed out while the outer ring 8 is left. Further, the tool 13 is pushed straight while applying an equal force at each position of the cross at the tip of the tool 13. Therefore, no oblique force is applied to the bearing 7,
The bearing 7 is pushed straight out without tilting. Therefore, the bearing 7 can be pushed out smoothly without being held in the recess 3.
