The present application will be described in detail below with reference to the drawings. Reference numeral 1 is a clamping band that clamps an oil filter. This clamping band 1 is made by bending a band-shaped elastic material into a cut circular shape, and both ends of the clamping band are bent outward. A pair of opposing locking pieces 2a and 2b are provided by bending the support piece 3, and a support piece 3 is provided horizontally projecting outward at a position diametrically opposed to the locking pieces 2a and 2b. ing. Reference numeral 4 denotes an inner cylindrical body on which the clamping band 1 is mounted on the inner periphery, and the inner cylindrical body 4 is integrally provided with a lid 7 having a through hole 6 in the center at the upper end of a cylindrical part 5. On the lower end opening side of the shaped part 5, there is a horizontal sliding hole 8 into which the locking pieces 2a, 2b of the clamping band 1 are slidably and commonly fitted, and the horizontal sliding hole 8 is diametrically opposed to the horizontal sliding hole 8, and Horizontal support holes 9 for slidably supporting the support pieces 3 of the band 1 and preventing vertical movement of the clamping band 1 are provided in each case. 1
0 is an outer cylinder into which the inner cylinder 4 is fitted, and the outer cylinder 10 has a lid 11 at the upper end of a cylindrical part 11 having an inner diameter slightly larger than the outer diameter of the inner cylinder 4. The lid body 11 and the lid body 7 of the inner cylindrical body 4 are rotatably connected via a connecting shaft 12 with a flange inserted into the through hole 6. Further, at a predetermined position in the circumferential direction on the lower end opening side of the outer cylinder 10, there is a holding piece 13 for maintaining a distance between the inner wall of the outer cylinder 10 and the outer wall of the inner cylinder 4;
As the inner cylinder body 4 rotates in the relative direction, the locking pieces 2a and 2b of the clamping band 1 change depending on the direction of rotation.
A pair of pressing pieces 14a and 14b are respectively protruded to press the inner wall of the outer cylinder 10 and the outer wall of the inner cylinder 4 in the same way as the holding piece 13. A protrusion 15 is provided on the outer peripheral surface of the outer cylinder 10 to prevent the hand from slipping, and the tip of a tool such as an offset handle is fitted into the center of the upper surface of the lid 11 of the outer cylinder 10. Square hole 16
A hexagonal prism-shaped operating portion 17 is protruded from the hexagonal column and has a hexagonal column shape that can be rotated with a tool such as a monkey wrench. A in the figure is an oil filter attached to an engine of an automobile or the like.

のである。 Therefore, when installing the oil filter A to an engine of an automobile, etc., the oil filter A is inserted into the inner cylinder body 4, and the mounting screw hole provided on the bottom surface of the oil filter A is inserted into the engine. It is screwed into the hollow connecting threaded pipe, and in this state, the outer cylinder body 10 is rotated in the screwing direction by hand or using a tool. That is, in the state shown in FIG.
Rotate 0 clockwise. Then, one of the pressing pieces 14a protruding inside the outer cylindrical body 10 presses one of the locking pieces 2a of the clamping band, and the clamping ring 1 rotates in the same direction along the inner peripheral surface of the inner cylindrical body 4. Then, the other locking piece 2b comes into contact with one end of the sliding hole 8 of the inner cylinder body 4. When the outer cylindrical body 10 is further rotated in the same direction in this state, the locking piece 2a receives a pressing force, and the clamping band 1 strongly clamps the oil filter A while decreasing its diameter as shown in FIG. 3b. Therefore, by continuing to rotate the outer cylindrical body 10 in one direction, there is no risk of slipping as would be the case when the oil filter A itself is rotated directly by hand, and it is possible to securely screw the oil filter A into the engine. . After this oil filter A is securely screwed into the engine, when the rotation operation of the outer cylinder body 10 is released, the clamping band 1 is restored to the state shown in FIG.
The attachment/detachment tool of the present application can be removed from the holder. In addition, when removing the oil filter A from the engine, fit the attaching/detaching tool of the present invention from above the oil filter, and move the outer cylindrical body 10 in the opposite direction to when attaching the oil filter to the engine. Rotate counterclockwise in Figure 3. Then, outer cylinder body 1
0 presses the other locking piece 2b, and the clamping band 1 locks into the inner cylindrical body 4.
The locking pieces 2a rotate in the same direction along the inner circumferential surface of the inner cylinder body 4, and the other locking piece 2a comes into contact with the other end of the sliding hole 8 of the inner cylinder body 4.
When the outer cylinder body 10 is further rotated in the same direction in this state, the clamping band 1 strongly clamps the oil filter A while decreasing its diameter, and therefore, by continuing to rotate the outer cylinder body 10 in the other direction. Unlike when the oil filter A itself is rotated directly by hand, there is no risk of slippage, and the oil filter can be easily removed from the engine.
