[0014] The embodiments of the present invention are listed below.

[0015] A push-on cap to be fitted into an air intake or exhaust port of a moving object includes a cap body that closes the air intake or exhaust port when fitted into the air intake or exhaust port and has a cap outer surface that faces the inner wall of the air intake or exhaust port, and a non-slip portion disposed on at least a portion of the cap outer surface of the cap body, the non-slip portion being formed of a material with a higher coefficient of friction than the cap outer surface and abutting against the inner wall of the air intake or exhaust port. The non-slip portion abutting against the inner wall of the air intake or exhaust port prevents the push-on cap from falling out of the air intake or exhaust port.

[0016] When the cap body is fitted into the intake or exhaust port, the anti-slip portion is located on a portion of the cap body near the front end in the direction in which the intake or exhaust port opens, and the rear side of the cap body in the direction in which the intake or exhaust port opens faces the intake or exhaust port. This allows the anti-slip portion to come into contact with the inner wall of the intake or exhaust port in the final stage of fitting, improving the ease of fitting the push-in cap into the intake or exhaust port.

[0017] The anti-slip portions are arranged at intervals in the circumferential direction of the cap body, thereby reducing the insertion force required to insert the push-on cap into the intake or exhaust port, thereby improving the ease of inserting the push-on cap into the intake or exhaust port.

[0018] The cap body includes an elastically deformable elastic material and a skin material covering the elastic material, the skin material constituting the outer surface of the cap. Elastic deformation of the elastic material allows the outer shape of the push-on cap to deform to correspond to the shape of the inner wall of the intake or exhaust port. This makes it easier to insert the push-on cap into the intake or exhaust port and prevents the push-on cap from falling off the intake or exhaust port.

[0019] The elastic material includes a soft elastic material located on the inner wall side of the intake or exhaust port when the cap body is fitted inside the intake or exhaust port, and a hard elastic material located on the opposite side of the inner wall of the intake or exhaust port and having a higher elastic modulus than the soft elastic material. The soft elastic material easily deforms, allowing the outer shape of the push-on cap to change to correspond to the inner shape of the intake or exhaust port. This reduces the insertion force required to insert the push-on cap into the intake or exhaust port. It also accommodates variations in the manufacturing dimensions of intake or exhaust ports. Furthermore, the hard elastic material maintains the outer shape of the push-on cap, thereby maintaining friction between the anti-slip portion and the inner wall of the intake or exhaust port. This prevents the push-on cap from falling off the intake or exhaust port.

[0020] The cap body includes a plurality of segments, each of which has an inner surface where the segments face each other and an outer surface where the segments face the inner wall of the intake or exhaust port, and the anti-slip portion is disposed on the outer surface of the segment. This improves workability compared to fitting a single large push-fit cap into the intake or exhaust port. Furthermore, the anti-slip portion on each of the segments prevents the segments from falling off the intake or exhaust port.

[0021] Furthermore, a pressing device is provided that presses the divided bodies in different directions to press the divided bodies against the inner wall of the intake or exhaust port, thereby firmly pressing the divided bodies against the inner wall of the intake or exhaust port, further preventing the push-in cap from falling off the intake or exhaust port.

[0022] The pressing device is disposed on one of the plurality of segments, and a pressing force receiving portion that receives the pressing force from the pressing device is disposed on the other segment. The pressing device includes a shaft that is elongated in a pressing direction in which the segment is pressed against the inner wall of the intake port or the exhaust port and that is movable in the pressing direction. The pressing force receiving portion includes a locking portion with which an end of the shaft abuts in the pressing direction, and a hooking portion with which a side surface of the shaft hooks from behind in the opening direction of the intake port or the exhaust port. The pressing force of the pressing device is received by the pressing force receiving portion, so that the plurality of segments are pressed against the inner wall of the intake port or the exhaust port. This further prevents the push-on cap from falling off the intake port or the exhaust port. Furthermore, the abutment of the end of the shaft with the locking portion presses the plurality of segments against the inner wall of the intake port or the exhaust port. This further prevents the push-on cap from falling off the intake port or the exhaust port. In addition, the hooking of the side of the shaft with the hook portion prevents the multiple segments from moving forward in the opening direction, further preventing the push-in cap from falling off the intake or exhaust port.

[0023] The pressing force receiving portion has a locking hole that is a bottomed hole drilled in the pressing direction, the bottom of the locking hole is the locking portion, and the inner surface of the locking hole is the hook portion. The locking portion and the hook portion can be formed by the simple method of forming the locking hole in the pressing force receiving portion.

[0024] Each of the plurality of segments has an anti-slip portion disposed on at least the outer surface of the segment that is pressed against the inner wall of the intake or exhaust port by the pressing device when the segment is pressed by the pressing device, thereby further preventing the push-in cap from falling off the intake or exhaust port.

[0025] Furthermore, the push-in cap may include a flexible hinge connecting adjacent segments, the hinge being disposed on the rear surface of the cap outer surface in the direction of the intake or exhaust port, so as to straddle adjacent edges of the adjacent segments. As a result, the position of the multiple segments can be easily adjusted when inserting the push-in cap into the intake or exhaust port, thereby improving the efficiency of the push-in cap assembly.

[0026] Furthermore, at least one of the plurality of segments includes a first hook portion, and at least one of the plurality of segments other than the segment including the first hook portion includes the first hook portion and a second hook portion that hooks from the front in the opening direction of the intake port or the exhaust port, and the engagement between the first hook portion and the second hook portion prevents at least the segment including the first hook portion and the segment including the second hook portion from moving in a direction that would cause them to fall off the intake port or the exhaust port. The simple technique of hooking the first hook portion and the second hook portion further prevents the push-on cap from falling off the intake port or the exhaust port.

[0027] The inner wall of the intake or exhaust port is tapered to become narrower as it approaches the back of the intake or exhaust port. When a push-on cap is fitted into an intake or exhaust port of this shape, the push-on cap is relatively easy to remove. In such cases, the push-on cap according to the present invention is effective.

[0028] A push-on cap is fitted into an intake or exhaust port of a moving body, the push-on cap including a cap body having a plurality of segments that closes the intake or exhaust port when fitted into the intake or exhaust port, and a pressing device that presses the segments in different directions to press the segments against an inner wall of the intake or exhaust port. Pressing the segments against the inner wall of the intake or exhaust port by the pressing device prevents the push-on cap from falling off the intake or exhaust port.

[0029] a cap body having an outer surface that faces an inner wall of the inlet or outlet; and a non-slip portion disposed on at least a portion of the outer surface of the cap body, the non-slip portion being formed of a material having a higher coefficient of friction than the outer surface of the cap and being in contact with the inner wall of the inlet or outlet; the cap body having a plurality of divided bodies, each of the plurality of divided bodies having an inner surface where the plurality of divided bodies face each other, and an outer surface where the plurality of divided bodies face the inner wall of the inlet or outlet. A method for assembling a push-in cap, in which a push-in cap having an anti-slip portion disposed on the outer surface of the segment is fitted into the intake port or the exhaust port, includes the steps of: inserting the multiple segments into the intake port or the exhaust port with the outer surfaces of the segments positioned rearward in the opening direction of the intake port or the exhaust port and the inner surfaces of the segments positioned forward in the opening direction; and pushing the ends of the multiple segments of the push-in cap inserted into the intake port or the exhaust port that are positioned forward in the opening direction rearward in the opening direction, so that the anti-slip portion abuts against the inner wall of the intake port or the exhaust port, thereby attaching the push-in cap to the intake port or the exhaust port in a non-removable state.

[0030] According to the above-described method for assembling the push-on cap, it is possible to prevent the push-on cap from falling off the intake or exhaust port.

[0031] The plurality of divided bodies have guide slopes on the outer surfaces of the divided bodies at rear positions in the opening direction, which are narrower as they go rearward in the opening direction, and the process of inserting the plurality of divided bodies into the intake port or the exhaust port includes a process of inserting the push-in cap into the intake port or the exhaust port while bringing the guide slopes into contact with the opening edge of the intake port or the exhaust port.

[0032] When attempting to insert the multiple segments into the intake or exhaust port from the front in the opening direction, the multiple segments make it difficult to see the intake or exhaust port. Therefore, by bringing the guide slopes formed on the multiple segments into contact with the opening edge of the intake or exhaust port, the multiple segments can be easily inserted into the intake or exhaust port.

[0033] After the step of pushing the ends of the plurality of segments that are located on the front side in the opening direction rearward in the opening direction, the inner surfaces of the plurality of segments are abutted against each other to prevent the plurality of segments from moving in a direction that would cause them to fall off the intake or exhaust port. By using the simple technique of abutting the ends of the plurality of segments that are opposite the inner wall of the intake or exhaust port against each other, it is possible to further prevent the push-in cap from falling off the intake or exhaust port.

[0034] The method further includes a step of pressing the divided bodies against an inner wall of the intake or exhaust port after the divided bodies are pushed rearward in the opening direction, thereby further preventing the push-in cap from falling off the intake or exhaust port.

[0035] a cap body that includes a plurality of divided bodies, and a pressing device that presses the divided bodies in different directions to press the divided bodies against an inner wall of the intake or exhaust port; a cap body that is fitted into an intake or exhaust port of a moving body and closes the intake or exhaust port when fitted into the intake or exhaust port; and a pressing device that presses the divided bodies in different directions to press the divided bodies against an inner wall of the intake or exhaust port; the push-in cap is attached to the intake or exhaust port in a non-removable state by using the pressing device to press the outer surfaces of the segments of the multiple segments against the inner wall of the intake or exhaust port.

[0036] According to the above-described method for assembling the push-on cap, it is possible to prevent the push-on cap from falling off the intake or exhaust port.

[0037] (Embodiment 1) A first embodiment will be described with reference to FIG. 1. A push-in cap 10a according to this embodiment is fitted into an air intake port 2 formed in a movable body 1. In the following description, the front of the movable body 1 in the direction of travel will be referred to as the front, and the rear will be referred to as the rear. The up-down direction will be the direction of gravity. The left-right direction will be the direction perpendicular to both the front-to-back direction and the up-to-down direction. However, the above directions are for the convenience of description and do not limit the invention. Furthermore, for multiple identical components, only some of the components will be assigned reference numerals, and the reference numerals may be omitted for other components.

[0038] 1. Configuration of Mobile Unit 1 1, an inlet 3 that opens downward is formed on the bottom surface of the moving body 1. The moving body 1 can be any moving body 1, such as a vehicle such as an automobile or motorcycle, or a ship. The inlet 3 is not limited to being formed on the bottom surface of the moving body 1, but may be formed in any position such as the top surface, right side surface, left side surface, front surface, or rear surface.

[0039] The inlet 3 according to this embodiment is formed so that the upward recess dimension increases toward the rear. An air intake 2 is formed at the rear end of the inlet 3. The air intake 2 opens forward inside the inlet 3. The air intake 2 is connected to an engine (not shown) and supplies air to the engine. The air intake 2 is formed in a hollow cylindrical shape that extends in the front-to-rear direction (an example of an opening direction) as a whole. In this embodiment, the inner wall of the air intake 2 is mirror-finished. Although not shown in detail, the inner wall of the air intake 2 is formed in a tapered shape that narrows toward the rear.

[0040] However, the inner wall of the intake port 2 does not have to be mirror-finished. Also, the inner wall of the intake port 2 may be formed to have the same inner diameter dimension in the front-to-rear direction, or may be formed in a tapered shape that becomes wider toward the rear.

[0041] The air intake 2 according to this embodiment is formed in the shape of an elongated hole that is long in the left-right direction. The air intake 2 is formed asymmetrically in the left-right direction. Furthermore, the air intake 2 is formed asymmetrically in the top-bottom direction. However, the shape of the air intake 2 is not limited to the above, and can be any shape, such as a circle, an ellipse, a track, or a polygonal shape such as a triangle or a square. Furthermore, the air intake 2 may be formed symmetrically in the left-right direction or in the top-bottom direction.

[0042] 2. Configuration of the push-on cap 10a As shown in Fig. 2, the push-on cap 10a is fitted into the air intake 2 of the vehicle 1 when the engine is stopped. This prevents wind, rain, sand, insects, small animals, and other foreign objects from entering through the air intake 2. As a result, engine malfunctions can be prevented.

[0043] As shown in Figures 2 and 3, push-on cap 10a is formed in a shape that follows the internal shape of intake port 2. As described above, intake port 2 is formed asymmetrically, and push-on cap 10a is also formed asymmetrically. Furthermore, intake port 2 is formed asymmetrically up and down, and push-on cap 10a is also formed asymmetrically up and down. However, push-on cap 10a may be formed symmetrically or vertically.

[0044] The push-on cap 10a includes a cap body 11 and an anti-slip portion 12. However, the anti-slip portion 12 may be omitted. The cap body 11 is divided into two parts in the left-right direction. The cap body 11 includes a first division 11a located on the right side and a second division 11b located on the left side. The left-right length of the first division 11a and the left-right length of the second division 11b are set to be approximately the same. The cap body 11 includes a cap outer surface 11c facing the inner wall of the intake port 2. The first division 11a and the second division 11b each include a division outer surface 11d facing the inner wall of the intake port 2. The first division 11a and the second division 11b each include a division inner surface 11e facing each other (see FIG. 9). In this embodiment, the first division 11a and the second division 11b have different shapes.

[0045] However, the cap body 11 may be configured to include three or more divided bodies. The divided bodies may have the same shape or different shapes.

[0046] (1) First divided body 11a As shown in Fig. 2, first segment 11a is formed in a generally rectangular shape that is elongated in the left-right direction when viewed from the front. As shown in Fig. 4, first segment 11a includes a front wall 13 located on the front side when push-in cap 10a is fitted into intake port 2, an upper wall 14 extending rearward from the upper end of front wall 13, and a lower wall 15 extending rearward from the lower end of front wall 13. The length of upper wall 14 in the front-to-rear direction is greater than the length of lower wall 15 in the front-to-rear direction.

[0047] As shown in FIG. 4, the first divided body 11a includes a core material 21, a hard elastic material 22, a soft elastic material 23, and a skin material 24.

[0048] The core material 21 is formed in the shape of a flat plate in the front-rear direction. The material constituting the core material 21 is not particularly limited, and any material such as resin, metal, rubber, etc. can be appropriately selected. Any resin such as polyamide, polyester, polyolefin, etc. can be selected as the resin. Any metal such as SUS, aluminum, etc. can be selected as the metal. Any rubber such as natural rubber, synthetic rubber, etc. can be selected as the rubber.

[0049] The core 21 constitutes the front wall 13. A hard elastic material 22 extending rearward is disposed on the upper edge of the core 21. The upper edge of the core 21 and the hard elastic material 22 may be bonded together. In addition, a hard elastic material 22 extending rearward is also disposed on the lower edge of the core 21. The lower edge of the core 21 and the hard elastic material 22 may be bonded together.

[0050] The hard elastic member 22 is made of an elastically deformable foamed resin. Any foamed resin can be selected as the foamed resin constituting the hard elastic member 22, such as foamed polyethylene, foamed polypropylene, or hard foamed polyurethane.

[0051] The hard elastic material 22 is laminated with a soft elastic material 23 having a lower elastic modulus than the hard elastic material 22. In other words, the hard elastic material 22 has a higher elastic modulus than the soft elastic material 23. The soft elastic material 23 is disposed outward of the hard elastic material 22 in the up-down direction. The thickness of the hard elastic material 22 in the up-down direction is set smaller than the thickness of the soft resin in the up-down direction. However, the thickness of the hard elastic material 22 in the up-down direction may be the same as the thickness of the soft resin in the up-down direction, or may be set smaller.

[0052] The soft elastic member 23 is made of an elastically deformable foamed resin. Suitable foamed resins that can be used to form the soft elastic member 23 include foamed rubbers such as natural rubber foam and synthetic rubber foam, and soft polyurethane.

[0053] When cap body 11 is fitted inside intake port 2, soft elastic material 23 is located on the inner wall side of intake port 2. Soft elastic material 23 easily deforms elastically, allowing cap body 11 to be easily fitted inside intake port 2. Furthermore, hard elastic material 22 allows cap body 11 to maintain its shape.

[0054] The cover material 24 covers the core material 21, the hard elastic material 22, and the soft elastic material 23. The outer surface of the cover material 24 forms the cap outer surface 11c. The material that forms the cover material 24 can be, for example, canvas, which is a woven fabric coated with a synthetic resin material such as vinyl chloride. The woven fabric is flexible.

[0055] As shown in FIG. 4, a front plate 31 is disposed on the front surface of the front wall 13 of the first divided body 11a. The front plate 31 according to this embodiment is made of metal and is formed slightly larger above, to the right, and below than the core material 21 when viewed from the front. Any metal can be selected as the metal constituting the front plate 31, such as stainless steel or aluminum. However, the front plate 31 may also be made of resin, such as polyolefin, polyamide, or polyester. The front plate 31 may also be omitted.

[0056] As shown in FIG. 4, a rear plate 32 is disposed on the rear surface of the front wall 13 of the first divided body 11a. The rear plate 32 is made of metal. The vertical length of the rear plate 32 is set to be approximately the same as that of the core material 21. The upper and lower ends of the rear plate 32 are bent rearward. This connects the front wall 13 to the upper wall 14 and the lower wall 15 via the rear plate 32. Any metal can be selected as the metal for forming the rear plate 32, such as stainless steel or aluminum. However, the rear plate 32 may also be made of resin, such as polyolefin, polyamide, or polyester. The rear plate 32 may also be omitted.

[0057] 4, the front plate 31, the skin material 24, the core material 21, and the rear plate 32 are fixed together by bolts 33 and nuts 34. However, the bolts 33 and nuts 34 may be sealed with a sealing member (not shown). The same applies to the following description.

[0058] As shown in FIGS. 2 and 3, a handle 35 is fixed to the front surface of the first divided body 11a. As shown in FIG. 3, the handle 35 is made of metal and is formed into a substantially U-shape when viewed from above. As shown in FIGS. 5 and 6, the handle 35 is fixed to the front panel 31, the skin material 24, the core material 21, and the rear panel 32 by bolts 33 that pass through the front panel 31, the skin material 24, the core material 21, and the rear panel 32. However, the material constituting the handle 35 is not particularly limited, and any material such as resin, leather, or cloth can be appropriately selected. Furthermore, the means for fixing the handle 35 to the first divided body 11a is not limited to bolt fastening, and any fixing means such as sewing or adhesive can be selected.

[0059] As shown in FIGS. 2 and 3, a toggle clamp 36 (an example of a pressing device) is fixed by a bolt 33 to a position on the front surface of the first divided body 11a near the left end. The toggle clamp 36 includes a base 36a, a shaft 36b, a lever 36c, and a stroke shaft 36d (an example of a shaft). The lever 36c is rotatable about the shaft 36b disposed on the base 36a. By rotating the lever 36c, the stroke shaft 36d moves left and right (an example of a pressing direction). In this embodiment, when the tip of the lever 36c is rotated in a direction approaching the front panel 31, the stroke shaft 36d moves leftward. However, the stroke shaft 36d may also move rightward when the tip of the lever 36c is rotated in a direction approaching the front panel 31.

[0060] However, the pressing device is not limited to the toggle clamp 36, but may be, for example, a shaft long in the left-right direction with a screw thread formed on its outer periphery, and any configuration can be appropriately selected.

[0061] 3, a chamfered guide slope 25 is formed on the right rear end of the upper wall 14 of the first divided body 11a. The guide slope 25 is formed to become narrower toward the rear in the opening direction of the intake port 2.

[0062] As shown in FIG. 5, a first anti-slip portion 12a is disposed on the right edge of the first segment 11a (on the right side surface of the top wall 14, the right side surface of the front wall 13, and the right side surface of the bottom wall 15). The first anti-slip portion 12a is formed of a material with a higher coefficient of friction than the covering material 24. The material constituting the first anti-slip portion 12a is not particularly limited, and any suitable material can be selected, such as rubbers such as natural rubber, synthetic rubber, and silicone rubber, or elastomers such as styrene-based thermoplastic elastomers, olefin-based thermoplastic elastomers, and dynamically crosslinked thermoplastic elastomers. Alternatively, the material constituting the first anti-slip portion 12a may be, for example, a woven fabric impregnated with rubbers such as natural rubber, synthetic rubber, and silicone rubber, or elastomers.

[0063] Although not shown in detail, a soft elastic material is disposed inside first anti-slip portion 12a. As a result, when first anti-slip portion 12a is pressed against the inner wall of intake port 2, the soft elastic material elastically deforms, generating a resilient force that urges first anti-slip portion 12a against the inner wall of intake port 2. As a result, first anti-slip portion 12a is strongly pressed against the inner wall of intake port 2. As a result, the frictional force between first anti-slip portion 12a and the inner wall of intake port 2 increases, preventing push-on cap 10a from falling off from intake port 2. However, a hard elastic material may be disposed inside first anti-slip portion 12a. Alternatively, the soft elastic material may be omitted.

[0064] (2) Second divided body 11b As shown in Figure 2, the second division body 11b is formed in a generally rectangular shape that is elongated in the left-right direction when viewed from the front. The first division body 11a and the second division body 11b are formed asymmetrically in the left-right direction. This prevents the second division body 11b from being inserted on the right side and the first division body 11a from being inserted on the left side when fitting the first division body 11a and the second division body 11b into the intake port 2.

[0065] 6, when the push-in cap 10a is fitted into the intake port 2, the second divided body 11b includes a front wall 13 located on the front side, an upper wall 14 extending rearward from the upper end of the front wall 13, and a lower wall 15 extending rearward from the lower end of the front wall 13. The length of the upper wall 14 in the front-to-rear direction is greater than the length of the lower wall 15 in the front-to-rear direction.

[0066] Although not shown in detail, like the first division 11a, the second division 11b includes a core material 21, a hard elastic material 22, a soft elastic material 23, and a skin material 24. The core material 21, the hard elastic material 22, the soft elastic material 23, and the skin material 24 that make up the second division 11b are the same as those in the first division 11a, and therefore a redundant description will be omitted.

[0067] As shown in Fig. 6, a front plate 31 is disposed on the front surface of the front wall 13 of the second divided body 11b. The front plate 31 is made of metal and is formed slightly larger above, to the right, and below than the core material 21 when viewed from the front. The metal constituting the front plate 31 can be any metal, such as stainless steel or aluminum.

[0068] As shown in FIG. 6, a rear plate 32 is disposed on the rear surface of the front wall 13 of the second divided body 11b. The rear plate 32 is made of metal. The vertical length of the rear plate 32 is set to be approximately the same as that of the core material 21. The upper and lower ends of the rear plate 32 are bent rearward. This connects the front wall 13 to the upper wall 14 and the lower wall 15 via the rear plate 32. Any metal can be selected as the metal for forming the rear plate 32, such as stainless steel or aluminum. However, the front plate 31 may also be made of resin, such as polyolefin, polyamide, or polyester. The front plate 31 may also be omitted.

[0069] As shown in FIG. 6, the front plate 31, the skin material 24, the core material 21, and the rear plate 32 are fixed together by bolts 33 and nuts 34.

[0070] 2 and 3, a handle 35 is fixed to the front surface of the second divided body 11b. As shown in Fig. 3, the handle 35 is formed in a substantially U-shape when viewed from above. The handle 35 is fixed to the front plate 31, the skin material 24, the core material 21, and the rear plate 32 by bolts 33 that pass through the front plate 31, the skin material 24, the core material 21, and the rear plate 32.

[0071] 2 and 3, a locking block 37 (an example of a pressing force receiving portion) is fixed to the front surface of the second divided body 11b at a position near the right end. The locking block 37 is fixed to the front plate 31 with a bolt 33.

[0072] There are no particular limitations on the material that constitutes the locking block 37, and any material can be selected, such as metals such as SUS and aluminum, and resins such as polyamide, polyester, polyolefin, etc. The locking block 37 is formed in a substantially rectangular parallelepiped shape.

[0073] 2 and 3, with first segment 11a and second segment 11b inserted into intake port 2, lever 36c of toggle clamp 36 is rotated and the tip of stroke shaft 36d abuts against the right side of locking block 37 from the right, thereby pressing first segment 11a to the right and second segment 11b to the left. As a result, the right side wall of first segment 11a is pressed against the inner wall of intake port 2, and the left side wall of second segment 11b is pressed against the inner wall of intake port 2. As a result, first segment 11a and second segment 11b are prevented from coming out of intake port 2.

[0074] 3, the left rear end portion of the upper wall 14 of the second divided body 11b is formed with a chamfered guide slope 25. The guide slope 25 is formed to become narrower toward the rear in the opening direction of the intake port 2.

[0075] As shown in FIG. 6 , a second anti-slip portion 12b is disposed on the left edge of the second segment 11b (the left side surface of the upper wall 14, the left side surface of the front wall 13, and the left side surface of the lower wall 15). The second anti-slip portion 12b is formed of a material with a higher friction coefficient than the covering material 24. The material of the second anti-slip portion 12b is not particularly limited, and any suitable material can be selected, such as rubbers such as natural rubber, synthetic rubber, and silicone rubber, or elastomers such as styrene-based thermoplastic elastomers, olefin-based thermoplastic elastomers, and dynamically crosslinked thermoplastic elastomers. The material of the second anti-slip portion 12b may be, for example, a woven fabric impregnated with rubbers such as natural rubber, synthetic rubber, and silicone rubber, or elastomers. The material of the second anti-slip portion 12b may be the same as or different from the material of the first anti-slip portion 12a.

[0076] Although not shown in detail, a soft elastic material is disposed inside second anti-slip portion 12b. As a result, when second anti-slip portion 12b is pressed against the inner wall of intake port 2, the soft elastic material elastically deforms, generating a resilient force that urges second anti-slip portion 12b against the inner wall of intake port 2. As a result, second anti-slip portion 12b is strongly pressed against the inner wall of intake port 2. As a result, the frictional force between second anti-slip portion 12b and the inner wall of intake port 2 increases, preventing push-on cap 10a from falling off from intake port 2. However, a hard elastic material may be disposed inside second anti-slip portion 12b. Alternatively, the soft elastic material may be omitted.

[0077] As shown in FIG. 3, the left end of the top wall 14 of the first division 11a and the right end of the top wall 14 of the second division 11b are connected by a hinge 26. The hinge 26 is flexible and formed in a long, rectangular shape. The hinge 26 may be glued or sewn to the first division 11a and the second division 11b. The length of the hinge 26 allows the first division 11a and the second division 11b to be spaced apart by a predetermined distance, while preventing the first division 11a and the second division 11b from being spaced apart by more than the length of the hinge 26.

[0078] The material constituting the hinge 26 is not particularly limited, and any material can be selected, such as cloth, leather, plastic, etc. The hinge 26 may be formed, for example, from canvas, which is a woven fabric coated with resin. The material constituting the hinge 26 and the material constituting the skin material 24 may be the same or different. However, the hinge 26 may be omitted.

[0079] 3. End processing of anti-slip portion 12 7 and 8, the fixing structure between the second anti-slip portion 12b and the covering material 24 will be described. However, for the sake of convenience, the hard elastic material 22 and the soft elastic material 23 are omitted from Fig. 7 and Fig. 8.

[0080] 7 shows the structure for fastening the left end of the second anti-slip portion 12b to the covering material 24. As shown in Fig. 7, the front edge of the second anti-slip portion 12b is folded inward together with the left edge of the covering material 24 covering the front surface of the second divided body 11b and the front edge of the covering material 24 covering the left side surface of the second divided body 11b, and is sewn with sewing thread 27. This prevents the front edge of the second anti-slip portion 12b from being exposed and forming a step, thereby preventing the thread from fraying from the front edge of the second anti-slip portion 12b.

[0081] Similarly, the rear edge of the second anti-slip portion 12b is folded inward together with the left edge of the skin material 24 covering the rear surface of the second divided body 11b and the rear edge of the skin material 24 covering the left side of the second divided body 11b, and is sewn with sewing thread 27. This prevents the rear edge of the second anti-slip portion 12b from being exposed and forming a step, thereby preventing the thread from fraying from the rear edge of the second anti-slip portion 12b.

[0082] 8, the upper edge of the second anti-slip portion 12b attached to the left edge of the top wall 14 of the second segment 11b is folded downward and sewn to the skin 24 covering the left side of the top wall 14 of the second segment 11b with sewing thread 27. The lower edge of the second anti-slip portion 12b attached to the left edge of the top wall 14 of the second segment 11b is folded inward and sewn to the lower edge of the skin 24 covering the left side of the top wall 14 of the second segment 11b with sewing thread 27. This prevents the formation of a step when the upper and lower edges of the second anti-slip portion 12b attached to the left edge of the upper wall 14 of the second divided body 11b are exposed, thereby preventing the thread from fraying from the upper and lower edges of the second anti-slip portion 12b attached to the left edge of the upper wall 14 of the second divided body 11b.

[0083] 8, the lower edge of the second anti-slip portion 12b attached to the left edge of the bottom wall 15 of the second segment 11b is folded upward and sewn with thread 27 to the skin 24 covering the left side of the bottom wall 15 of the second segment 11b. The upper edge of the second anti-slip portion 12b attached to the left edge of the bottom wall 15 of the second segment 11b is folded inward and sewn with thread 27 together with the upper edge of the skin 24 covering the left side of the bottom wall 15 of the second segment 11b and the left edge of the skin 24 covering the upper surface of the bottom wall 15 of the second segment 11b. This prevents the formation of a step when the upper and lower edges of the second anti-slip portion 12b attached to the left edge of the lower wall 15 of the second divided body 11b are exposed, thereby preventing the thread from fraying from the upper and lower edges of the second anti-slip portion 12b attached to the left edge of the lower wall 15 of the second divided body 11b.

[0084] The fixing structure between the first anti-slip portion 12a and the covering material 24 is the same as the fixing structure between the second anti-slip portion 12b and the covering material 24, so a duplicated explanation will be omitted.

[0085] 4. Push-in cap 10a assembly and removal process 3 and 9-10, a process for assembling the push-on cap 10a to the air intake 2 and a process for removing the push-on cap 10a from the air intake 2 will be described. However, the process for assembling the push-on cap 10a to the air intake 2 and the process for removing the push-on cap 10a from the air intake 2 are not limited to the following description.

[0086] 9, by rotating the lever 36c of the toggle clamp 36, the stroke shaft 36d of the toggle clamp 36 is moved to the right. The first divided body 11a and the second divided body 11b are arranged so as to be bent with the hinge 26 as an axis.

[0087] In other words, with the first division 11a and the second division 11b arranged side by side in the longitudinal direction of the intake port 2, the ends of the first division 11a and the second division 11b near the center in the longitudinal direction protrude forward in the opening direction of the intake port 2. In other words, with the division inner surfaces 11e of the first division 11a and the second division 11b facing each other, the end on the division inner surface 11e side protrudes forward in the opening direction of the intake port 2.

[0088] In the above state, the operator can easily perform the work by gripping the handle 35.

[0089] While gripping the handle 35, the operator brings the first segment 11a and the second segment 11b close to the intake port 2 from the front. The guide slopes 25 of the first segment 11a and the guide slopes 25 of the second segment 11b come into contact with the opening edge of the intake port 2. The guide slopes 25 of the first segment 11a and the guide slopes 25 of the second segment 11b act as guides, allowing the first segment 11a and the second segment 11b to be inserted into the intake port 2. When attempting to insert the first segment 11a and the second segment 11b into the intake port 2 from the front, the first segment 11a and the second segment 11b make it difficult to see the intake port 2. Therefore, a configuration in which the guide slopes 25 of the first segment 11a and the guide slopes 25 of the second segment 11b act as guides is effective.

[0090] Furthermore, first segment 11a and second segment 11b are pressed forward to insert first segment 11a and second segment 11b into intake port 2 as shown in FIG. 10. In this state, first anti-slip portion 12a of first segment 11a may abut against the inner wall of intake port 2, and second anti-slip portion 12b of second segment 11b may abut against the inner wall of intake port 2. In this case, first segment 11a and second segment 11b can be positioned within intake port 2. However, first anti-slip portion 12a and second anti-slip portion 12b may be separated from the inner wall of intake port 2 in the state shown in FIG. 10.

[0091] 3, the lever 36c of the toggle clamp 36 is rotated to move the stroke shaft 36d to the left. As a result, the left end of the stroke shaft 36d comes into contact with the right side surface of the locking block 37 from the right. As a result, the outer surfaces 11d of the first and second segments 11a, 11b are pressed against the inner wall of the intake port 2.

[0092] As a result, first anti-slip portion 12a on the right wall of first segment 11a is pressed from the left against the inner wall of intake port 2. Similarly, second anti-slip portion 12b on the left wall of second segment 11b is pressed from the right against the inner wall of intake port 2. Because the coefficient of friction of first anti-slip portion 12a and second anti-slip portion 12b is greater than that of skin material 24, they adhere closely to the inner wall of intake port 2. This fixes first segment 11a and second segment 11b inside intake port 2 in a non-removable state.

[0093] When removing the push-on cap 10a from the intake port 2, the lever 36c of the toggle clamp 36 is rotated to move the stroke shaft 36d to the right. This separates the tip of the stroke shaft 36d from the locking block 37. As a result, the frictional force between the first anti-slip portion 12a and the inner wall of the intake port 2 is reduced, and the frictional force between the second anti-slip portion 12b and the inner wall of the intake port 2 is also reduced.

[0094] Next, the worker grasps the handle 35 and pulls the first divided body 11a and the second divided body 11b forward in the opening direction.

[0095] 5. Effects of this form Next, the effects of this embodiment will be described. The push-on cap 10a according to this embodiment is fitted into the air intake 2 of the movable body 1. The push-on cap 10a includes a cap body 11 and an anti-slip portion 12. The cap body 11 closes the air intake 2 when fitted into the air intake 2. The cap body 11 also includes a cap outer surface 11c that faces the inner wall of the air intake 2. The anti-slip portion 12 is disposed on at least a portion of the cap outer surface 11c of the cap body 11. The anti-slip portion 12 is formed of a material with a higher coefficient of friction than the cap outer surface 11c, and abuts against the inner wall of the air intake 2. The abutment of the anti-slip portion 12 against the inner wall of the air intake 2 holds the push-on cap 10a in a non-detachable state from the air intake 2. This prevents the push-on cap 10a from falling off the air intake 2.

[0096] Cap body 11 includes elastically deformable hard elastic material 22 and soft elastic material 23, and skin material 24 that covers hard elastic material 22 and soft elastic material 23. Skin material 24 forms cap outer surface 11c. Elastic deformation of hard elastic material 22 or soft elastic material 23 allows the outer shape of push-on cap 10a to deform in accordance with the shape of the inner wall of intake port 2. This makes it easier to fit push-on cap 10a into intake port 2 and prevents push-on cap 10a from falling off intake port 2.

[0097] The soft elastic material 23 is located on the inner wall side of the intake port 2 when the cap body 11 is fitted inside the intake port 2. The hard elastic material 22 is located on the opposite side from the inner wall of the intake port 2 when the cap body 11 is fitted inside the intake port 2. The hard elastic material 22 has a higher elastic modulus than the soft elastic material 23. The soft elastic material 23 easily deforms, allowing the outer shape of the push-on cap 10a to change to correspond to the inner shape of the intake port 2. As a result, the insertion force required to insert the push-on cap 10a into the intake port 2 can be reduced. This also makes it possible to accommodate variations in the manufacturing dimensions of the intake port 2. Furthermore, the hard elastic material 22 maintains the outer shape of the push-on cap 10a, thereby maintaining the frictional force between the non-slip portion 12 and the inner wall of the intake port 2. This prevents the push-on cap 10a from falling off the intake port 2.

[0098] The cap body 11 includes a first segment 11a and a second segment 11b. Each of the first segment 11a and the second segment 11b has a segment inner surface 11e where the first segment 11a and the second segment 11b face each other, and a segment outer surface 11d where the first segment 11a and the second segment 11b face the inner wall of the intake port 2. An anti-slip portion 12 is disposed on the segment outer surface 11d. This improves workability compared to fitting a single large push-fit cap into the intake port 2. Furthermore, the first segment 11a and the second segment 11b are prevented from falling off the intake port 2.

[0099] Furthermore, a toggle clamp 36 is provided that presses the first divided body 11a and the second divided body 11b in a direction different from the intake port 2, thereby pressing the first divided body 11a and the second divided body 11b against the inner wall of the intake port 2. This allows the first divided body 11a and the second divided body 11b to be firmly pressed against the inner wall of the intake port 2, further preventing the push-on cap 10a from falling off the intake port 2.

[0100] When first divided body 11a and second divided body 11b are pressed by toggle clamp 36, first anti-slip portion 12a and second anti-slip portion 12b are disposed on at least the surface of cap outer surface 11c that is pressed against the inner wall of intake port 2 by toggle clamp 36. This further prevents push-on cap 10a from falling off from intake port 2.

[0101] Each of the first and second divided bodies 11a, 11b has an anti-slip portion 12 disposed on at least the surface of the divided body outer surface 11d that is pressed against the inner wall of the intake port 2 by the pressing device when the first and second divided bodies 11a, 11b are pressed by the toggle clamp 36. This further prevents the push-on cap 10a from falling off the intake port 2.

[0102] Furthermore, the cap is provided with a flexible hinge 26 connecting the first and second segments 11a and 11b, the hinge 26 being disposed on the rear surface of the cap outer surface 11c in the opening direction of the intake port 2, straddling adjacent edges of the first and second segments 11a and 11b. As a result, when inserting the push-in cap 10a into the intake port 2, the positions of the first and second segments 11a and 11b can be easily adjusted, improving the efficiency of the assembly work of the push-in cap 10a.

[0103] The toggle clamp 36 is fixed to a metal front plate 31 that is fixed to the cap body 11. When the toggle clamp 36 presses against the first and second divided bodies 11a, 11b, a relatively large force is applied to the toggle clamp 36. Because the toggle clamp 36 is fixed to the metal front plate 31, the force applied by the toggle clamp 36 to the first and second divided bodies 11a, 11b is prevented from being reduced. This further prevents the push-on cap 10a from falling off the intake port 2.

[0104] The inner wall of the intake port 2 is tapered to become narrower as it approaches the back of the intake port 2. When the push-on cap 10a is fitted into an intake port 2 having such a shape, the push-on cap 10a is relatively easy to remove. In such cases, the push-on cap 10a according to this embodiment is effective.

[0105] This embodiment also provides a push-on cap 10a that is fitted into the air intake 2 of a movable body 1, and includes a cap body 11 that closes the air intake 2 when fitted into the air intake 2, and that includes a first divided body 11a and a second divided body 11b, and a toggle clamp 36 that presses the first divided body 11a and the second divided body 11b in different directions to press the first divided body 11a and the second divided body 11b against the inner wall of the air intake 2. The toggle clamp 36 presses the first divided body 11a and the second divided body 11b against the inner wall of the air intake 2, thereby preventing the push-on cap 10a from falling off the air intake 2.

[0106] This embodiment is a method for assembling a push-in cap 10a, and includes the steps of: inserting the first and second segments 11a and 11b into the air intake 2 with the segment outer surfaces 11d of the first and second segments 11a and 11b positioned rearward in the opening direction of the air intake 2 and the segment inner surfaces 11e of the first and second segments 11a and 11b positioned forward in the opening direction; and pushing the ends of the first and second segments 11a and 11b of the push-in cap 10a inserted into the air intake 2 that are positioned frontward in the opening direction rearward in the opening direction, so that the ends of the first and second segments 11a and 11b on the air intake 2 side abut against the inner wall of the air intake 2, thereby attaching the push-in cap 10a to the air intake 2 in a non-removable state.

[0107] According to the above-described method for assembling the push-on cap 10a, the push-on cap 10a can be prevented from falling off the intake port 2.

[0108] The first and second divided bodies 11a and 11b have guide slopes 25 formed at the rear position in the opening direction on the divided body outer surface 11d, which are narrower as they go rearward in the opening direction, and the process of inserting the first and second divided bodies 11a and 11b into the air intake 2 includes a process of inserting the push-in cap 10a into the air intake 2 while bringing the guide slopes 25 into contact with the opening edge of the air intake 2.

[0109] When first segment 11a and second segment 11b are inserted into intake port 2 from the front in the opening direction, first segment 11a and second segment 11b make it difficult to see the opening edge of intake port 2. Therefore, by bringing guide slopes 25 formed on first segment 11a and second segment 11b into contact with the opening edge of intake port 2, first segment 11a and second segment 11b can be easily inserted into intake port 2.

[0110] After the step of pushing the ends of the first divided body 11a and the second divided body 11b located on the front side in the opening direction rearward in the opening direction, the divided body inner surfaces 11e of the first divided body 11a and the second divided body 11b are abutted against each other, thereby preventing the first divided body 11a and the second divided body 11b from moving in a direction that would cause them to fall off the intake port 2. This further prevents the first divided body 11a and the second divided body 11b from falling off the intake port 2.

[0111] The method includes a step of pushing first divided body 11a and second divided body 11b rearward in the opening direction, and then pressing first divided body 11a and second divided body 11b against the inner wall of intake port 2. This further prevents push-on cap 10a from falling off intake port 2.

[0112] This embodiment is a method for assembling a push-in type cap 10a to fit the push-in type cap 10a into the intake port 2, and includes inserting the first divided body 11a and the second divided body 11b into the intake port 2 in a state in which the ends of the first divided body 11a and the second divided body 11b that are located on the inner wall side of the intake port 2 are arranged on the rear side in the opening direction, and the ends of the first divided body 11a and the second divided body 11b that are located opposite the inner wall of the intake port 2 are arranged on the front side in the opening direction. the step of pushing the ends of the first and second divided bodies 11a, 11b inserted into the intake port 2 that are located on the front side in the opening direction rearward in the opening direction; and the step of pressing the first and second divided bodies 11a, 11b against the inner wall of the intake port 2 by using a toggle clamp 36 to press the divided body outer surfaces 11d of the first and second divided bodies 11a, 11b in different directions, thereby attaching the push-in cap 10a to the intake port 2 in a non-removable state.

[0113] According to the above-described method for assembling the push-on cap 10a, the push-on cap 10a can be prevented from falling off the intake port 2.

[0114] (Embodiment 2) Next, a second embodiment will be described with reference to Fig. 11. In a push-on cap 10b according to this embodiment, a locking hole 37a is formed on the right side surface of a locking block 37 facing leftward. The locking hole 37a is a bottomed hole having a bottom 37b (an example of a locking portion). The inner surface of the locking hole 37a is an example of a hook portion and a second hook portion.

[0115] When the lever 36c of the toggle clamp 36 is rotated and the stroke shaft 36d moves leftward, the tip of the stroke shaft 36d is inserted into the locking hole 37a. Furthermore, the tip of the stroke shaft 36d presses the bottom 37b of the locking hole 37a to the right. This presses the left side surface of the second divided body 11b against the inner wall of the intake port 2, and as a reaction, presses the right side surface of the first divided body 11a against the inner wall of the intake port 2.

[0116] When the stroke shaft 36d is inserted into the locking hole 37a, the side surface of the stroke shaft 36d is hooked onto the inner side surface of the locking hole 37a from the rear in the opening direction. The stroke shaft 36d is an example of a first hook portion.

[0117] Note that, among the symbols used in the second and subsequent embodiments, the same symbols as those used in the previous embodiments represent the same components, etc. as those in the previous embodiments, unless otherwise specified.

[0118] In the push-on cap 10b according to this embodiment, the toggle clamp 36 is elongated in the left-right direction and includes a stroke shaft 36d that is movable in the left-right direction. The locking block 37 includes a bottom 37b of a locking hole 37a against which the end of the stroke shaft 36d abuts in the left-right direction, and an inner surface of the locking hole 37a against which the side of the stroke shaft 36d engages from the rear in the opening direction. The abutment between the end of the stroke shaft 36d and the bottom 37b of the locking hole 37a presses the first segment 11a and the second segment 11b against the inner wall of the intake port 2. This further prevents the push-on cap 10b from falling off the intake port 2. Furthermore, the engagement of the side of the stroke shaft 36d with the inner surface of the locking hole 37a prevents the longitudinal center portions of the first segment 11a and the second segment 11b from moving forward in the opening direction. This further prevents the push-in cap 10b from falling off the intake port 2.

[0119] Furthermore, a stroke shaft 36d is disposed in the first divided body 11a, and an inner surface of a locking hole 37a is formed in the second divided body 11b. The locking hole 37a has an inner surface that engages with the side surface of the stroke shaft 36d when the cap body 11 is fitted into the intake port 2. The engagement between the side surface of the stroke shaft 36d and the inner surface of the locking hole 37a prevents the first divided body 11a and the second divided body 11b from moving in a direction that would cause them to fall off the intake port 2.

[0120] However, the configuration of the second catch portion is not limited to the inner surface of the locking hole 37a, and the side surface of the stroke shaft 36d may be formed in a plate shape that can be engaged from the rear or front.

[0121] (Embodiment 3) Next, a third embodiment will be described with reference to Fig. 12. In a push-on cap 10c according to this embodiment, soft elastic members 23 are disposed above and below a core member 21. This reduces the insertion force required to insert the push-on cap 10c into the intake port 2.

[0122] Although not shown in detail, hard elastic materials 22 may be arranged above and below core material 21. In this case, frictional force between first anti-slip portion 12a and second anti-slip portion 12b and the inner wall of intake port 2 can be maintained, thereby preventing push-on cap 10c from coming off intake port 2.

[0123] However, the modulus of elasticity of the elastic material is not limited to the above, and an elastic material having any modulus of elasticity can be used.

[0124] (Embodiment 4) Next, a fourth embodiment will be described with reference to Figures 13 to 15. In a push-on cap 10d according to this embodiment, a third anti-slip portion 12c is arranged in a portion facing the inner surface of the intake port 2, near the front end of the push-on cap 10.

[0125] 13, third anti-slip portion 12c is formed on the upper surface of top wall 14 of first segment 11a at a position near the front end and has a shape elongated in the left-right direction, and is also formed on the upper surface of top wall 14 of second segment 11b at a position near the front end and has a shape elongated in the left-right direction. In a portion of the upper surface of top wall 14 of first segment 11a that is rearward of third anti-slip portion 12c in the front-rear direction, cap outer surface 11c is exposed and faces the inner wall of intake port 2.

[0126] Although not shown in detail, the third anti-slip portion 12c is formed in a left-right elongated shape at a position near the front end of the underside of the bottom wall 15 of the first segment 11a, and is also formed in a left-right elongated shape at a position near the front end of the underside of the bottom wall 15 of the second segment 11b. Furthermore, at a portion of the underside of the bottom wall 15 of the second segment 11b that is rearward of the third anti-slip portion 12c in the front-rear direction, the cap outer surface 11c is exposed and faces the inner wall of the intake port 2.

[0128] 15, the second anti-slip portion 12b according to this embodiment is formed on the left side surface of the second divided body 11b, at a position closer to the front end. In the area behind the second anti-slip portion 12b, the cap outer surface 11c is exposed and faces the inner wall of the intake port 2.

[0129] According to this embodiment, when the cap body 11 is fitted into the air intake 2, the anti-slip portion 12 is located in a portion of the cap body 11 near the front end in the opening direction, and the rear side of the cap body 11 in the opening direction has the cap outer surface 11c facing the inner wall of the air intake 2. As a result, the anti-slip portion 12 comes into contact with the inner wall of the air intake 2 and generates frictional force during the final stage of inserting the first divided body 11a and the second divided body 11b into the air intake 2. This improves the ease of fitting the push-in cap 10d into the air intake 2.

[0130] (Embodiment 5) Next, a fifth embodiment will be described with reference to Fig. 16.

Fourth anti-slip portions 12d are arranged side by side at intervals in the circumferential direction of push-in cap 10f.

[0136] As shown in Figure 18, the first anti-slip portion 12a in this embodiment is formed in a shape that is elongated in the front-to-rear direction on the right side of the upper wall 14 of the first divided body 11a, and is also formed in a shape that is elongated in the front-to-rear direction on the right side of the lower wall 15 of the first divided body 11a.

[0137] Also, as shown in Figure 19, the second anti-slip portion 12b in this embodiment is formed in a shape that is elongated in the front-to-rear direction on the left side surface of the upper wall 14 of the second divided body 11b, and is also formed in a shape that is elongated in the front-to-rear direction on the left side surface of the lower wall 15 of the second divided body 11b.

[0138] According to this embodiment, first anti-slip portion 12a, second anti-slip portion 12b, and fourth anti-slip portion 12d are formed to be elongated in the front-rear direction, which reduces the insertion force required to insert first divided body 11a and second divided body 11b into intake port 2.

[0139] (Embodiment 7) Next, a seventh embodiment will be described with reference to Fig. 20. In a push-in cap 10g according to this embodiment, the first divided body 11a does not include a front plate 31. The first divided body 11a also does not include a toggle clamp 36.
