Description

  The present invention relates to a vehicle wheel. Specifically, the present invention relates to a vehicle wheel including a vehicle wheel body having an opening.

  Conventionally, it has been proposed to mount an annular support body that supports a vehicle tire from the inside when the internal pressure is reduced on the rim of the vehicle wheel body (see, for example, Patent Document 1). Is difficult to insert into the vehicle tire if the shape is as it is, and it is not possible to get over the rim flange. A support is mounted on the rim.

However, even if the support is divided, it is extremely difficult to insert the divided piece into the vehicle tire through the gap between the vehicle wheel body and the vehicle tire.
In addition, it is known that high functionality of a vehicle tire can be realized by disposing a predetermined instrument or the like in the vehicle tire.

  From this point of view, a technique for forming an opening in a vehicle wheel body has been proposed. For example, Patent Document 2 proposes a technique for forming a hole in a vehicle wheel body and closing the hole with a screw. Yes.

JP 2001-239814 A JP 2003-285602 A

  By the way, when the opening is formed in the vehicle wheel main body, a decrease in the strength of the vehicle wheel main body is unavoidable, and in particular, the strength around the opening is considered to be significantly reduced. If the holes formed in the wheel main body are simply plugged with screws, there is a risk that safe driving may be hindered due to a decrease in strength of the vehicle wheel main body caused by forming the opening.

  The present invention was devised in view of the above points, and an object of the present invention is to provide a vehicle wheel that can compensate for a decrease in strength of a vehicle wheel body due to the formation of an opening. is there.

  In order to achieve the above object, in the vehicle wheel according to the present invention, in the vehicle wheel comprising a vehicle wheel body having an opening in a rim and a lid portion closing the opening, the vehicle wheel The main body is provided in a peripheral region of the opening and has a protruding portion that protrudes inward or outward in the radial direction of the vehicle wheel main body, and the lid portion needs reinforcement in the peripheral region of the opening. A reinforcing portion that covers at least a part of the portion to be formed, and a concave portion or a hole portion that is provided in the reinforcing portion and fits with the protruding portion.

Here, the reinforcement part covers at least a part of the area that needs reinforcement in the peripheral region of the opening part, so that the reduction in the strength of the vehicle wheel body due to the formation of the opening part can be compensated. In other words, the thickness of the peripheral region of the opening can be increased by the reinforcing portion, and the decrease in the strength of the vehicle wheel body can be compensated for by increasing the thickness.
In addition, although it is thought that the decrease in the strength of the vehicle wheel body due to the formation of the opening can be compensated by increasing the thickness of the material itself constituting the vehicle wheel body, the vehicle wheel body When the overall thickness of the vehicle is increased, the weight of the vehicle wheel body is increased, so that this method is not appropriate.

In addition, the vehicle wheel body is provided with a protrusion, and the lid is provided with a recess or a hole that fits into the protrusion, whereby the reinforcing portion and the vehicle wheel body can be firmly fixed. .
That is, in general, the vehicle wheel body is often constituted by a relatively thin member, and even if the lid is fixed to the vehicle wheel body constituted by such a thin member by, for example, screwing, It is difficult to achieve strong fixation. On the other hand, the vehicle wheel body is provided with a protrusion, and the lid is provided with a recess or a hole. When the protrusion and the recess or hole are fitted, the vehicle wheel body is relatively Even if it is constituted by a thin member, as described above, a sufficiently strong fixation is possible.

  For example, like the vehicle wheel described in Japanese Patent No. 4110202, when the fitting portion that fits the opening provided in the rim of the vehicle wheel main body is provided in the lid portion, the opening is provided. When the portion and the fitting portion are fitted, the lid portion and the vehicle wheel body can be firmly fixed. On the other hand, as described above, when the vehicle wheel main body is provided with the protruding portion and the lid portion is provided with a recess or a hole to be fitted with the protruding portion, the vehicle wheel main body is provided with the rim. Even when the fitting portion that fits into the opening is not provided in the lid portion, the lid portion and the vehicle wheel body can be firmly fixed.

  Further, since the lid portion and the vehicle wheel body can be firmly fixed, the air chamber can be sufficiently sealed.

  By the way, the lid may be fixed to the inside of the vehicle wheel body, that is, to the inside of the vehicle wheel body in the radial direction, or to the outside of the vehicle wheel body, that is, to the outside of the vehicle wheel body in the radial direction. May be. However, considering the convenience of attaching and detaching the lid to the vehicle wheel body, it is preferable that the lid is configured to be fixed to the inside of the vehicle wheel body.

  The “vehicle” herein includes a vehicle for transporting a cargo passenger such as an automobile, a motorcycle, a bicycle, a train, and an aircraft, and is not limited to a so-called automobile.

  Further, in the vehicle wheel according to the present invention, the vehicle wheel body having an opening in the rim, the opening is closed, and the vehicle wheel body is disposed radially inward of the vehicle wheel body. A vehicle wheel comprising: a lid portion; and a fixing tool that is disposed radially inward of the vehicle wheel body from the lid portion and sandwiches the lid portion with the vehicle wheel body. The vehicle wheel body has a thick portion provided in a peripheral region of the opening and formed with a concave portion into which the fixing tool can be screwed, and the lid portion is a periphery of the opening. It has the reinforcement part which coat | covers at least one part of the location which needs reinforcement among area | regions.

  Here, the reinforcement part covers at least a part of the area that needs reinforcement in the peripheral region of the opening part, so that the reduction in the strength of the vehicle wheel body due to the formation of the opening part can be compensated.

  Further, since the concave portion to which the fixing tool can be screwed is formed in the thick portion, the vehicle wheel body and the fixing tool can be firmly fixed in a state where the lid portion is sandwiched, and as a result, the vehicle wheel Strong fixation between the main body and the lid can be realized. In general, the vehicle wheel body is formed of a relatively thin member, but the concave portion can be formed by forming the thick portion.

  Further, in the vehicle wheel according to the present invention, the vehicle wheel main body having an opening in the rim, the opening is closed, and the vehicle wheel main body is disposed on the outer side in the radial direction of the vehicle wheel main body. And a lid that is disposed radially inward of the vehicle wheel body with respect to the vehicle wheel body, and that has a state in which the vehicle wheel body is sandwiched between the lid portion and the vehicle wheel body. The lid portion is provided in a region corresponding to a peripheral region of the opening, and includes a thick portion in which a concave portion capable of screwing the fixing tool is formed, and a peripheral region of the opening And a reinforcing portion that covers at least a part of a portion that requires reinforcement.

  Here, the reinforcement part covers at least a part of the area that needs reinforcement in the peripheral region of the opening part, so that the reduction in the strength of the vehicle wheel body due to the formation of the opening part can be compensated.

  Further, since the concave portion to which the fixing tool can be screwed is formed in the thick portion, the lid portion and the fixing tool can be firmly fixed in a state where the vehicle wheel body is sandwiched, and as a result, the vehicle wheel Strong fixation between the main body and the lid can be realized.

  In the vehicle wheel to which the present invention is applied, it is possible to compensate for the decrease in the strength of the vehicle wheel body due to the formation of the opening.

Hereinafter, embodiments of the present invention will be described with reference to the drawings to provide an understanding of the present invention.
FIG. 1 is a schematic view for explaining an example of a vehicle wheel to which the present invention is applied. A vehicle wheel 1 shown here is composed of a vehicle wheel body 2 and a lid 3.
In the vehicle wheel body 2 described above, a circular opening 4 is formed in the rim, and the area around the opening (area indicated by symbol A in the drawing) is directed radially inward of the vehicle wheel body. A protrusion 5 is provided. The lid 3 is formed with a reinforcing portion 6 that covers at least a part of the peripheral area of the opening, and the reinforcing portion is formed with a hole 7 that fits into the protruding portion.

  The center side of the vehicle wheel body of the protrusion 5 has a circular shape with a smaller diameter than the opposite side of the center of the vehicle wheel body of the protrusion, and the side surface of the protrusion 5 has a tapered shape. There is no. The reinforcing portion 6 is formed to extend in four directions that form an angle of 45 degrees with the turning direction of the vehicle wheel body 2. Furthermore, the vehicle wheel main body 2 and the lid 3 are fixed by fitting the protrusion 5 into the hole 7.

  Here, in this embodiment, the vehicle wheel main body in which the circular opening 4 is formed is described as an example, but the shape of the opening 4 formed in the vehicle wheel main body 2 is not necessarily circular. There is no need for a shape, and any shape may be used. However, if the opening is formed in the vehicle wheel body, the possibility of cracking starting from the opening is higher than when the opening is not formed. It is thought that it is effective to make the configuration of the opening that makes it difficult to concentrate, that is, it is considered effective to make the opening circular or elliptical, It is preferable to form the opening. From the viewpoint of suppressing stress concentration points as much as possible, it is considered that a circular shape is preferable to an elliptical shape.

  Further, it is sufficient that the reinforcing portion 6 covers at least a part of the peripheral region of the opening 4, and is necessarily formed by extending in a direction that forms an angle of 45 degrees with the circumferential direction of the vehicle wheel body 2. Although not necessary, in order to compensate for the decrease in the strength of the vehicle wheel body 2 due to the formation of the opening 4 in the vehicle wheel body 2, the rotation direction of the vehicle wheel body 2 and a predetermined angle (however, It is preferable that the reinforcing portion 6 is formed by extending in a direction that forms an angle of 45 degrees with the rotation direction of the vehicle wheel body 2. It is considered that the formation of is preferable.

FIG. 2 is a schematic view for explaining another example of a vehicle wheel to which the present invention is applied. A vehicle wheel 1 shown here is composed of a vehicle wheel main body 2 and a lid 3.
In the vehicle wheel main body 2 described above, a circular opening 4 is formed in the rim, as in the example of the vehicle wheel to which the present invention is applied. In a region indicated by A), a protruding portion 5 is provided toward the inside in the radial direction of the vehicle wheel body. Further, the lid portion 3 is formed with a reinforcing portion 6 that covers at least a part of the peripheral region of the opening portion, and further, the reinforcing portion is formed with a concave portion 8 that fits with the protruding portion.

  The center side of the vehicle wheel body of the protrusion 5 has a circular shape with a smaller diameter than the opposite side of the center of the vehicle wheel body of the protrusion, and the side surface of the protrusion 5 has a tapered shape. There is no. The reinforcing portion 6 is formed to extend in the circumferential direction of the vehicle wheel body 2 and the width direction of the vehicle wheel body 2. Furthermore, the vehicle wheel body 2 and the lid 3 are fixed by fitting the protrusion 5 into the recess 8.

  Here, the point that the shape of the opening 4 formed in the vehicle wheel main body 2 is not necessarily circular is the same as that of the vehicle wheel to which the present invention is applied.

  Further, it is sufficient that the reinforcing portion 6 covers at least a part of the peripheral region of the opening 4, and the reinforcing portion 6 is not necessarily formed by extending in the circumferential direction of the vehicle wheel body 2 and in the width direction of the vehicle wheel body 2. There is no need to

  In the example of the vehicle wheel to which the present invention is applied and the other example of the vehicle wheel to which the present invention is applied, the opening 4 is formed because the reinforcing region 6 covers the peripheral region of the opening 4. As a result, a decrease in strength of the vehicle wheel main body 2 can be compensated, and even if the opening 4 is formed in the vehicle wheel main body 2, it is possible to obtain sufficient strength to withstand running.

  In one example of a vehicle wheel to which the present invention is applied and another example of a vehicle wheel to which the present invention is applied, the vehicle wheel main body 2 and the lid are fitted by fitting the protruding portion 5 and the hole portion 7 or the concave portion 8. The part 3 can be firmly fixed. Further, since the vehicle wheel body 2 and the lid 3 can be firmly fixed, an air chamber formed between the vehicle wheel body 2 and the vehicle tire attached to the vehicle wheel body 2. Can be sufficiently secured.

  Although JP 2003-285602 A proposes a technique of forming a hole in a vehicle wheel body and closing the hole with a screw, the vehicle wheel body is generally composed of a relatively thin member. In many cases, the technology for closing the hole by simply screwing the vehicle wheel body constituted by such thin members does not sufficiently secure the screw to the vehicle wheel body. It is difficult to keep the chamber sealed. In consideration of the point that the air chamber must be kept in a sealed state, the technique described in Japanese Patent Application Laid-Open No. 2003-285602 is perfect to form a small opening and can be inserted into a hand or a tool. In reality, it is extremely difficult to form a large opening.

  Here, in one example of the vehicle wheel to which the present invention is applied and another example of the vehicle wheel to which the present invention is applied, the lid portion 3 is located on the inner side of the rim of the vehicle wheel body 2 (the vehicle wheel body). The case where the cover 3 is disposed on the center side is described as an example, but the lid 3 does not necessarily have to be disposed on the inner side of the rim, and is disposed on the outer side of the rim (the center side of the vehicle wheel body). May be arranged on the opposite side (see FIG. 3A (a)). When the lid portion is disposed outside the rim, the projecting portion 5 is provided toward the outer side in the radial direction of the vehicle wheel body. What is the center side of the vehicle wheel body of the projecting portion 5? The opposite side is preferably configured to have a circular shape with a smaller diameter than the center side of the vehicle wheel body of the protruding portion.

  In particular, when the lid portion 3 is disposed outside the rim, it is preferable to form the grip portion 15 on the lid portion for convenience when the lid portion 3 is fixed to the vehicle wheel body 2. (See FIG. 6B.) That is, when the lid 3 is attached to the vehicle wheel main body 2, the vehicle wheel main body 2 can be very easily and firmly secured by gripping the grip portion by hand or hooking a tool or the like on the grip portion. In particular, when the lid portion 3 is disposed outside the rim, it is preferable that the grip portion 15 is formed on the lid portion.

  In consideration of the workability of attaching the lid portion, it is preferable that the lid portion is arranged inside the rim rather than the outside of the rim.

  By the way, in the example of the vehicle wheel to which the present invention is applied and the other example of the vehicle wheel to which the present invention is applied, the case where nothing is fitted in the opening 4 formed in the rim is taken as an example. As shown in FIGS. 3A (b) and 3A (c), the lid 3 is provided with a fitting portion 9 that fits the opening 4 formed in the rim. May be. In the case of the fitting portion 9 shown in FIG. 3A (b), the opposite side to the center side of the vehicle wheel body 2 has a circular shape with a smaller diameter than the center side of the vehicle wheel body 2, It is preferable that the side surface of the fitting portion 9 is formed to have a tapered shape. Similarly, in the case of the fitting portion 9 shown in FIG. 3A (c), the center side of the vehicle wheel body 2 has a circular shape with a smaller diameter than the side opposite to the center side of the vehicle wheel body 2. It is preferable that the side surface of the fitting portion 9 is formed to have a tapered shape.

  Further, in the above-described example of the vehicle wheel to which the present invention is applied and the other example of the vehicle wheel to which the present invention is applied, the case where the rim is a uniform thickness is described as an example. As shown in FIG. 3B (d) or FIG. 3B (e), the peripheral region A of the opening 4 may be configured to be thick. By configuring the peripheral area A of the opening 4 to be thick, it is possible to more fully compensate for the strength reduction of the vehicle wheel body 2 due to the formation of the opening 4.

  Moreover, as a modification of an example of the vehicle wheel to which the present invention is applied, as shown in FIG. 4A, an outer diameter substantially the same as the inner diameter of the vehicle wheel main body 2 is provided inside the vehicle wheel main body 2. An annular ring body 10 having a ring shape is disposed, and the lid 3 is pressed in the outer direction of the vehicle wheel body 2 (from the center direction of the vehicle wheel body to the direction opposite to the center direction of the vehicle wheel body). Thus, the reduction in the strength of the vehicle wheel body 2 due to the formation of the opening 4 can be more fully compensated, and the air chamber can be more sufficiently sealed. Even if the ring body is smaller than the inner diameter of the vehicle wheel main body 2, the lid portion 3 is disposed on the inner side of the lid portion 3, and the ring portion 10 that contacts the lid portion 3 is arranged, so that the lid portion 3 is made to be a vehicle wheel. It is possible to press the outer side of the main body 2, and more fully compensate for the decrease in the strength of the vehicle wheel main body 2 due to the formation of the opening 4, and the air chamber is more fully sealed. Can be secured.

  Moreover, as another modification of an example of the vehicle wheel to which the present invention is applied, as shown in FIG. 4B, the opening 4 is formed by connecting the lids 3 adjacent to each other. It is possible to more sufficiently compensate for the decrease in the strength of the vehicle wheel body 2 due to the above, and it is possible to further sufficiently ensure the airtightness of the air chamber.

  In addition, when the vehicle wheel body is provided with a support body that supports the inner wall of the vehicle tire body in order to realize run-flat running of the vehicle tire, the load and impact received by the vehicle tire are passed through the support body. Therefore, since the vehicle wheel body 2 is received, the strength of the vehicle tire body 2 is further required. Therefore, when the vehicle wheel main body 2 is provided with a support body, the region corresponding to the mounting position of the support body is covered with the reinforcing portion 6 so that the load and impact received through the support body can be sufficiently obtained. It becomes possible to respond.

  In addition, when the cover part 3 is fixed to the vehicle wheel main body 2, the fitting part 9 is configured to support or support the inner wall of the vehicle tire main body 2. The vehicle tire can be run flat without providing a separate support (see FIG. 8).

  FIG. 5A is a schematic view for explaining still another example of a vehicle wheel to which the present invention is applied. The vehicle wheel 1 shown here includes a vehicle wheel main body 2, a lid 3, and a fixing tool. 11.

  A circular opening 4 is formed in the rim of the vehicle wheel main body 2 described above, and a protrusion 5 is provided in a region around the opening toward the inside in the radial direction of the vehicle wheel. Further, the protruding portion 5 is provided with a convex portion 12 provided with a screw groove on its side surface.

  The lid 3 is formed with a reinforcing portion 6 that covers at least a part of the peripheral area of the opening, and the reinforcing portion is formed with a hole 7 that fits into the protruding portion.

  Further, the fixing tool 11 is provided with a concave portion 13 provided with a screw groove on its side surface, and is configured to be screwable to the protruding portion 5 by screwing the convex portion 12 into the concave portion 13.

  Here, in the present embodiment, the case where the protrusion 12 is separately provided in the protrusion 5 is described as an example, but it is sufficient if the fixing tool 11 is configured to be screwable to the protrusion 5. For example, as shown in FIG. 6A, a screw groove is formed on the side surface of the distal end region of the protruding portion 5, and the protruding portion 5 is screwed into the recessed portion 13 so that the fixing tool 11 is screwed to the protruding portion 5. It is good also as composition to do.

In the present embodiment, the lid 3 is described as an example in which the lid 3 is not connected to any connected body that supports any tire function. However, the lid 3 and the connected body that supports the tire function are used. By configuring so as to be connectable, the function of the vehicle wheel is improved.
That is, when the pressure of the air chamber formed between the vehicle wheel main body and the vehicle tire main body mounted on the vehicle wheel main body decreases, or the probability that the pressure of the air chamber decreases is high. In such a case, it is preferable that the air chamber can be connected to a connected body that assists the tire function by maintaining the pressure of the air chamber in a normal state or by suppressing the pressure drop of the air chamber. Specifically, the connected body for assisting the tire function includes (1) an atmospheric pressure detector for detecting the internal pressure of the air chamber, and (2) a damaged portion of the vehicle tire main body when the pressure of the air chamber decreases. A sealing agent sprayer that sprays the sealing agent on the air chamber, and (3) a high-pressure tank or an air-filled tank for supplementing the pressure of the air chamber when the pressure of the air chamber decreases are conceivable.

  FIG. 5B is a schematic view for explaining still another example of the vehicle wheel to which the present invention is applied. The vehicle wheel 1 shown here is fixed to the vehicle wheel body 2 and the lid 3. It consists of the tool 11.

  A circular opening 4 is formed in the rim of the vehicle wheel main body 2 described above, and a protrusion 5 is provided in a region around the opening toward the inside in the radial direction of the vehicle wheel. Further, the protrusion 5 is provided with a recess 13 having a screw groove on its side surface.

  The lid 3 is formed with a reinforcing portion 6 that covers at least a part of the peripheral area of the opening, and the reinforcing portion is formed with a hole 7 that fits into the protruding portion.

  Furthermore, the fixing tool 11 is provided with a convex portion 12 provided with a screw groove on its side surface, and can be screwed to the protruding portion 5 by screwing the convex portion 12 into the concave portion 13.

Here, in FIG. 5A and FIG. 5B, the case where the hole 7 that fits the protruding portion 5 is formed is described as an example, but the above-described present invention is applied. As another example of the vehicle wheel, a recess 8 that fits into the protrusion 5 may be formed (see FIGS. 5C and 5D). In addition, when the recessed part 8 fitted with the protrusion part 5 is formed, the through-hole 14 which the convex part 12 penetrates in the bottom face of the recessed part 8 will be formed.
Here, when the concave portion 8 is formed, in other words, when the lid portion 3 is configured to be thicker than the protruding portion 5, the bottom surface of the concave portion 8 is sandwiched between the protruding portion 5 and the fixing tool 11. Thus, the lid 3 can be more firmly fixed by the vehicle wheel body 2.

  In still another example of the vehicle wheel to which the present invention is applied and still another example of the vehicle wheel to which the present invention is applied, the fixing member 11 is screwed by screwing the convex portion 12 into the concave portion 13. The case is described as an example. However, it is sufficient that the fixing tool 11 is configured to be fixed to the vehicle wheel body 2 so as to form a state in which the lid 3 is sandwiched between the vehicle wheel body 2 and the vehicle wheel body 2. The fixing method of 2 and the fixing tool 11 is not necessarily limited to the screwing method by screwing the convex portion 12 into the concave portion 13.

  In still another example of the vehicle wheel to which the present invention is applied and still another example of the vehicle wheel to which the present invention is applied, not only the protrusion 5 and the hole 7 are fitted, but also the vehicle wheel. By sandwiching the lid portion 3 between the main body 2 and the fixing tool 11, the vehicle wheel main body 2 and the lid portion 3 can be more firmly fixed.

  FIG. 7 is a schematic view for explaining still another example of a vehicle wheel to which the present invention is applied. The vehicle wheel 1 shown here is a vehicle wheel main body 2 in which an opening 4 is provided in a rim. And an air chamber formed between the vehicle wheel main body 2 and the vehicle tire main body 60 attached to the vehicle wheel main body (hereinafter, It is simply referred to as an “air chamber”) and is configured by a support 50 that supports the vehicle tire body. In addition, the reinforcement part 6 of the cover part 3 is comprised so that the area | region corresponding to the attachment position of the support body 50 may be coat | covered.

  The above-described support body 50 includes an adhering portion 51 attached to the vehicle wheel body 2 and a linking body 53 configured to be detachable, and a support portion 52 connected to the linking body and supporting the vehicle tire body. Thus, the support 50 is configured to be brought into the air chamber through the opening 4. Then, the support body 50 brought into the air chamber through the opening 4 is inserted with a hand or a tool from the opening 4 to attach the connecting body 53 to the fixing portion 51.

  In this embodiment, the case where the support 50 can be brought into the air chamber through the opening 4 is described as an example. However, the support 50 can be brought into the air chamber. For example, it is not always necessary to bring the support body 50 into the air chamber via the opening 4, and the support body 50 is mounted by mounting the vehicle tire body with the support body 50 placed on the rim of the vehicle wheel body 2. You may bring it into the air chamber. That is, the support 50 does not necessarily have to be configured to be brought into the air chamber through the opening 4. In the case where the support body 50 is brought into the air chamber by mounting the vehicle tire body with the support body 50 placed on the rim of the vehicle wheel body 2, the opening portion is also provided in the same manner as in the present embodiment. 4, a hand or a tool is put in and the connecting body 53 is attached to the fixing portion 51.

  In this embodiment, the case where the support body 50 is configured to be brought into the air chamber through the opening 4 as it is is described as an example. However, the support body 50 can be divided. For example, the support body 50 is configured so as to be divided into a connection body 53 and a support portion 52, and the connection body 53 and the support portion 52 are separately brought into the air chamber via the opening 4. You may comprise a support body combining both.

  Further, in the present embodiment, the description is given by taking the support attached to the vehicle wheel body 2 as an example. However, the support is not necessarily attached to the vehicle wheel body 2, and the cover 3 is not necessarily attached. It may be attached.

  The support body 50 is brought into the air chamber via the opening 4 and the connecting body 53 is attached to the fixing portion 51, and then the opening 4 is closed by the lid portion 3 to seal the air chamber.

  In still another example of the vehicle wheel to which the present invention is applied, a support body that supports the inner wall of the vehicle tire body is provided on the vehicle wheel body in order to realize run-flat running of the vehicle tire. The vehicle wheel body receives the load and impact received by the vehicle tire through the support. In addition, since the vehicle wheel main body receives the load and impact received by the vehicle tire via the support, the strength of the vehicle wheel main body 2 is further required. In still another example of the applied vehicle wheel, the region corresponding to the mounting position of the support body is covered with the reinforcing portion, so that it is possible to sufficiently cope with the load and impact received through the support body. .

  FIG. 9A is a schematic diagram for explaining still another example of a vehicle wheel to which the present invention is applied. The vehicle wheel 1 shown here includes a vehicle wheel main body 2, a lid 3, and a fixing tool. 11.

  A circular opening 4 is formed in the rim of the vehicle wheel body 2 described above, and a thick portion 30 is provided in the peripheral region of the opening. Further, the thick portion 30 is provided with a recess 31 provided with a screw groove on its side surface.

  The lid 3 is provided with a reinforcing portion 6 that covers at least a part of the peripheral region of the opening, and is formed with a through-hole 14 through which a convex portion of a fixture described later is inserted.

  Further, the fixing tool 11 is provided with a convex portion 33 provided with a thread groove on the side surface thereof, and is configured to be screwed to the vehicle wheel body by screwing the convex portion 33 into the concave portion 31. .

  FIG. 9B is a schematic view for explaining still another example of a vehicle wheel to which the present invention is applied. The vehicle wheel 1 shown here includes a vehicle wheel main body 2, a lid 3, and a fixing tool. 11.

  A circular opening 4 is formed in the rim of the vehicle wheel body 2 described above, and a through-hole 32 is formed in the peripheral region of the opening through which a convex portion of a fixture described later is inserted.

  Further, the lid portion 3 is provided with a thick portion 30 at a location corresponding to the through hole. Further, the thick portion 30 is provided with a recess 31 provided with a screw groove on its side surface.

  Further, the fixing tool 11 is provided with a convex portion 33 provided with a screw groove on its side surface, and is configured to be screwed to the lid portion by screwing the convex portion 33 into the concave portion 31.

  In yet another example of the vehicle wheel to which the present invention is applied as shown in FIGS. 9A and 9B, the peripheral portion of the opening 4 is covered with the reinforcing portion 6. The reduction in strength of the vehicle wheel main body 2 due to the formation can be compensated, and even if the opening 4 is formed in the vehicle wheel main body 2, it is possible to obtain sufficient strength to withstand running.

  Further, the vehicle wheel body and the lid can be firmly fixed by screwing the fixing tool, and formed between the vehicle wheel body 2 and the vehicle tire mounted on the vehicle wheel body 2. The air chamber can be sufficiently sealed.
