2 surrounds and seals the supply port 111 and the discharge port 112. The oil sent from the supply port 111 to the oil filter 12 is filtered and flows out from the discharge pipe 121 to the discharge pipe 121.

FIGS. 3A and 3B show the receiving plate 13. FIG. The receiving plate 13 is formed of a semi-arc surface plate. The accommodation plate 13 can be bent and deformed in a direction in which the interval H between the arc ends 131 and 132 is changed. Three supporting pieces 14, 15, 16 are bent at equal intervals at the leading edge 133 of the storage plate 13, and supporting holes 141, 151, 161 are formed through the supporting pieces 14, 15, 16 respectively. Have been. Note that the support pieces 14, 15, 16 do not necessarily have to be at equal intervals. The support pieces 14, 15, 16 are the storage plate 1
3 is bent at approximately 90 ° to the outer peripheral surface side. The base edge of the storage plate 13 is covered with a rubber seal 17. Supporting pieces 18, 19, 20 are fixed to the outer peripheral surface of the storage plate 13 on the side of the seal 17. Each support piece 18, 19, 20 has a support hole 181, 191, 201.
Are provided so as to face the support holes 141, 151, and 161. In this embodiment, each support hole 141, 15
The diameters of 1,161,181,191,201 are the same, but need not be the same. Each support piece 18, 1
Positioning pieces 182, 192, and 202 are formed on the reference numerals 9 and 20 so as to be bent from the leading edge 133 toward the seal 17 side.

A suction pipe 21 is attached to the inner peripheral surface of the housing plate 13. The position of the suction pipe 21 is preferably at the lowest position of the arc. In the present embodiment, the center of the arc of the storage plate 13 is the lowest position of the arc, and the suction pipe 21
In the center of the arc. A suction port 211 is cut out at the base end of the suction pipe 21.

As shown in FIGS. 1B and 2B,
Three screw holes 22, 23, 24 are formed in the outer wall 11 around the oil filter 12. Screw holes 22, 2
The diameter of 3, 24 is larger than the diameter of screws 25, 26, 27. In FIG. 1B, the housing plate 13 indicated by a two-dot chain line has a natural shape.
2, 23, 24 and support holes 141, 151, 161, 18
1, 191 and 201 do not overlap each other.

When the oil filter 12 is to be replaced, as shown in FIG. 3B, screws 25, 26, 27 are inserted into each pair of support holes 141, 181, support holes 151, 191 and support holes 161, 201. Through. In this state, the accommodation plate 13 is bent from the natural shape of FIG. 1B as shown in FIG. 2B, and the tips of the screws 25, 26, 27 and the screw holes 22, 23, 24 are opposed to each other. In this facing state, the tips of the screws 25, 26, 27 are inserted into the screw holes 22, 23, 24, and the positioning pieces 182, as shown in FIG.
The storage plate 13 is pressed against the outer wall 11 so that the supply ports 192 and 202 abut against the outer wall 11 which is the wall where the supply port 111 and the discharge port 112 are formed. Positioning pieces 182, 192, 2
02 is in contact with the outer wall 11 and the seal 17 is
1 and the base end of the suction pipe 21 is
Abut.

In the state shown in FIG. 2 (b), the storage plate 13 which has been bent and deformed is about to be restored, and due to this restoring force, the tips of the screws 25, 26 and 27 which are the locking members are screw holes 22 which are the locking holes. , 23, 24. When the screws 25, 26, 27 are turned in the direction of the arrow R in FIGS. 1A and 2B in this locked state, the screws 25, 26, 27 enter the screw holes 22, 23, 24 and are accommodated. The plate 13 is pressed against the outer wall 11 side. By this pressing, the seal 17 is firmly joined to the outer wall 11, and the housing plate 13 is firmly held at the housing position shown in FIG.

When the oil filter 12 is removed from the mounting position with respect to the outer wall 11, oil remaining in the oil filter 12 leaks from the discharge pipe 121 or the inlet 123. The leaked oil travels along the outer wall 11, and the leaked oil Y traveling along the outer wall 11 is blocked by the storage plate 13 as shown in FIG. When the hose 28 is connected to the suction pipe 21 and suction is performed, the leaked oil Y blocked by the storage plate 13 is suctioned and discharged from the suction port 211 of the suction pipe 21.

After the suction and discharge of the leaked oil Y, the storage plate 13
Are bent from the state shown in FIG.
If the tip of the screw is not caught between the screw holes 22, 23, and 24, the screws 25, 26, and 27 can be used together with the accommodation plate 13.

The screws 25, 26, and 27 can be easily attached to and detached from the housing 4 while appropriately adjusting the bending deformation shape of the storage plate 13. Also, screws 25, 26, 27 and screw holes 22, 23, 2
When the screws 25, 26, 27 are turned in the screwing direction in the locked state with the positioning member 4, the positioning pieces 182, 192, 202 and the seal 17 are rotated.
Is pressed against the outer wall 11 so that the storage plate 13 can be firmly held at the storage position. (1-3) The arc shape of the storage plate 13 is suitable for causing bending deformation. (1-4) The leaked oil Y blocked by the storage plate 13 is sucked and discharged through the suction pipe 21. Suction pipe 2
The suction and discharge of the leaked oil Y utilizing the method 1 is effective in reducing the adhesion residue of the leaked oil Y on the outer wall 11.

Next, a second embodiment shown in FIGS. 4A and 4B will be described. The same components as those in the first embodiment are denoted by the same reference numerals. The oil filter 12 according to this embodiment includes an engine outer wall 11 that is inclined downward.
It is attached to. A blocking plate 134 is fixed to the leading edge 133 of the storage plate 13.
A suction pipe 29 is attached to 4. Supporting piece 1
5 is formed integrally with the dam plate 134. The leaked oil Y is stored in a corner formed by the storage plate 13 and the dam plate 134 as shown in FIG. Dam board 1
34 makes it difficult to bend and deform the central portion of the arc of the storage plate 13, but the arc ends 131 and 132 of the storage plate 13.
The side is easily bent and deformed. Therefore, the screws 25, 26, 2
The bending and deforming operation of the housing plate 13 performed to engage the screw holes 7 with the screw holes 22, 23, and 24 is as easy as in the first embodiment.

In this embodiment, the same effects as in the first embodiment can be obtained. In the second embodiment, the leaked oil Y stored in the corner formed by the storage plate 13 and the dam plate 134 can be discarded by removing the storage plate 13 from the storage position. Therefore, the suction pipe 29 can be omitted in the second embodiment.

Next, a third embodiment shown in FIGS. 5A and 5B will be described. The same components as those in the first embodiment are denoted by the same reference numerals. In this embodiment, an arc-shaped positioning groove 30 is formed in the outer wall 11, and the seal 17 fits into the positioning groove 30. The seal 17 fits into the positioning groove 30 exactly,
The storage plate 13 is held at the storage position by the elastic deformation restoring force and the elastic deformation restoring force of the seal 17 fitted in the positioning groove 30.

In this embodiment, the configuration is simpler than in the first embodiment. Next, FIG. 6A and FIG.
An embodiment will be described. The same components as those in the first embodiment are denoted by the same reference numerals.
