It is a part that is placed in That is, when the pedal engaging claw portion 231 rotates around the rotation axis N, the outermost edge portion 234 draws the outermost circular arc locus R1 of the pedal engaging claw portion 231 .
Similarly, the innermost edge portion 235 is a portion arranged on the radially innermost side among the portions positioned on the radial straight line P1. That is, when the pedal engaging claw portion 231 rotates about the rotation axis N, the innermost edge portion 235 draws the innermost circular arc locus R2 on the innermost side of the pedal engaging claw portion 231 .
The radial straight line P1 is an imaginary straight line extending radially from the center point P. As shown in FIG.
Reference numeral 533 indicates the outermost edge of the cleat engaging portion 53, and reference numeral 534 indicates the innermost edge of the cleat engaging portion 53, which are provided in the same manner as the outermost edge 234 and the innermost edge 235. .

Further, the pedal engaging claw portion 231 includes a region at least partially extending from the tip of the pedal engaging wall portion 232 in the release direction S2. In other words, the shape of the pedal engagement pawl does not necessarily have to be directed in the release direction S2, but it is designed to engage and release the cleat engagement portion 53 in the circumferential direction S, which will be described later. At least a part thereof should extend in the release direction S2. For example, the pedal engaging pawl may have a polygonal shape such as a triangular shape, a square shape, or another shape, and the overall shape may be oriented in a direction that intersects the radial straight line P1.

An engaging space K is defined. The surface extension surface 212 is an imaginary surface that is flush with the surface of the pedal base portion 21 in the pedal hole portion 211 . The engaging space K has the same shape and size as the pedal engaging claw portion 231 or larger in plan view. Since the height dimension of the pedal engagement wall portion 232 is equal to or greater than the thickness dimension of the cleat engagement pawl portion 531, the height dimension of the engagement space K with respect to the surface extension surface 212 is equal to that of the cleat. The thickness is equal to or greater than the thickness of the engaging claw portion 531 .

Further, as shown in FIG. 2, the cleat 50 is provided on the bottom portion SH1 of the shoe SH. The bottom portion SH1 is provided with a recess SH2, and the cleat 50 is provided in the recess SH2 so that the cleat 50 is recessed into the shoe SH from the bottom portion SH1 and does not protrude downward from the bottom portion SH1. Note that the cleat 50 may protrude downward from the bottom portion SH1.
The cleat 50 includes a cleat base portion 51, a cleat rotation connection portion 52, and a cleat engagement portion 53, as shown in FIGS.
The cleat 50 has the same shape and size as the binding 20, and the cleat 50 is upside down with respect to the binding 20 in FIGS.
That is, the cleat base portion 51, the cleat rotation connection portion 52, and the cleat engagement portion 53 have the same shape and size as the pedal base portion 21, the pedal rotation connection portion 22, and the pedal engagement portion 23, respectively. In particular, the shape and number of installation of the pedal engaging portions 23 are the same as the shape and number of installation of the cleat engaging portions 53 .
Therefore, description of the cleat 50 here is omitted.
Reference numeral 521 indicates a cleat recess, reference numeral 511 indicates a cleat hole portion, reference numeral 531 indicates a cleat engaging claw portion, and reference numeral 532 indicates a cleat engaging wall portion. Further, reference numeral 524 indicates a crack prevention sheet.
In addition, the cleat rotation connection magnet portion 522 and the pedal rotation connection magnet portion 222 are provided so that the magnets have different polarities when they are vertically inverted and opposed to each other.

Next, the use of the pedals 10, cleats 50, pedal system 3 and bicycle 1 according to embodiments of the present invention will be described.
As shown in FIG. 1, when the driver sits on the saddle 2d and holds the handlebar 2b and steps on the pedal 10, the crank portion 2h rotates, thereby rotating the rear wheel 2e via the chain wheel 2f and the chain 2g. do. Then, the bicycle 1 advances by continuously stepping on and lifting the pedals 10 by the driver. At this time, by engaging the pedal 10 and the cleat 50, the force for pulling down the pedal 10 and the force for pulling up the pedal 10 can be effectively used.

Here, the connection operation between the pedal 10 and the cleat 50 will be described.
In addition, the cleat 50 shall be attached in recessed part SH2 of shoes SH.
When the driver places the shoe SH on the pedal 10, the pedal contact surface 223 of the pedal rotation connection magnet portion 222 and the cleat connection surface 523 of the cleat rotation connection magnet portion 522 are magnetically attracted and connected to each other.
If the joint surfaces of the magnets have the same shape, the same area, and different polarities, when the magnets are attracted to each other by the magnetic force and joined together, the central axes extending in the thickness direction are aligned and the relative positions of the joint surfaces are changed. It has the ability to always join in the same relative position without radial displacement. That is, such a pair of magnets are always joined to each other in the same relative position with their center axes aligned.
That is, the pedal joint surface 223 and the cleat joint surface 523 are always joined at the same relative position with the rotation axis N aligned.
Therefore, by simply placing the shoes SH on the pedals 10 by the driver, the rotation axes N of the pedal rotation connection magnet portion 222 and the cleat rotation connection magnet portion 522 can be easily adjusted without being conscious of matching the rotation axes N of the pedal rotation connection magnet portion 222 and the cleat rotation connection magnet portion 522. The two can be connected according to the

In addition, when the joint surfaces of the magnet are joined to each other, a large force is required to move the one joint surface and the other joint surface apart so as to move them parallel to each other in the central axis direction. On the other hand, even if the joint surfaces are joined to each other, relative rotation with the central axis as the axis of rotation requires less force than the above-mentioned separating force.
Therefore, even if the pedal joint surface 223 and the cleat joint surface 523 are attracted and joined by magnetic force, the pedal rotation connection magnet portion 222 and the cleat rotation connection magnet portion 522 can be easily moved relative to each other around the rotation axis N as the rotation center. can be rotated.
That is, in a state in which the pedal contact surface 223 and the cleat contact surface 523 are magnetically attracted and joined by placing the shoe SH on the pedal 10, the rider simply rotates the heel toward the inside of the bicycle main body 2 to operate the pedal. The rotary connection magnet portion 222 and the cleat rotary connection magnet portion 522 can be easily rotated relative to each other with the rotation axis N as the center of rotation.
The relative rotation means that the pedal rotation connection portion 22 and the cleat rotation connection portion 52 rotate relative to each other. It includes the rotation of only the pedal rotation connection portion 22 with the rotation connection portion 52 fixed and the rotation of both the pedal rotation connection portion 22 and the cleat rotation connection portion 52 .

Then, when the driver rotates the heel inward, the pedal engaging portion 23 and the cleat engaging portion 53 rotate relative to each other around the rotation axis N as shown in FIG. 9A and approach each other. It moves relatively in the circumferential direction S as shown. As the heel is further rotated in the same direction, the pedal engaging claw portion 231 enters the engagement space K of the cleat engaging portion 53, and the cleat engaging claw portion 531 is also engaged with the pedal engaging portion 23. It invades into the joint space K. Finally, as shown in FIG. 9B, the peripheral edge of the pedal engaging claw portion 231 comes into contact with the inner peripheral surface 538 of the cleat engaging wall portion 532, and the peripheral edge of the cleat engaging claw portion 531 portion also contacts the inner peripheral surface 238 of the pedal engaging wall portion 232 , and the pedal engaging portion 23 and the cleat engaging portion 53 are engaged in the circumferential direction S.
In this manner, the pedal rotation connection magnet portion 222 and the cleat rotation connection magnet portion 522 are attracted to each other, and the pedal engaging portion 23 and the cleat engaging portion 53 are engaged in the circumferential direction S. are concatenated.

On the other hand, in order to release the connection between the pedal 10 and the cleat 50, the operation opposite to that described above should be performed. That is, when the rider rotates the heel outward of the bicycle main body 2, the pedal engaging portion 23 and the cleat engaging portion 53 relatively move in the circumferential direction S so as to separate from each other. combination is canceled.
Even if the joint surfaces of the magnets are joined to each other, when the magnets are pulled apart in the direction intersecting the central axis, a force smaller than the force required to separate them in parallel with the central axis as described above is sufficient.
Therefore, when the driver slides the shoe SH in a direction intersecting with the rotation axis N or lifts the heel, the pedal rotation connection magnet portion 222 and the cleat rotation connection magnet portion 522 are separated, and the pedal 10 and the cleat 50 are separated from each other. can be easily disconnected from

As described above, according to the pedal 10, the cleat 50, the pedal system 3, and the bicycle 1 of the present embodiment, the driver puts the shoe SH on the pedal 10 and connects the pedal rotation connection portion 22 and the cleat rotation connection portion 52. In this state, the pedal engaging portion 23 and the cleat engaging portion 53 can be engaged and disengaged in the circumferential direction S simply by rotating the heel. Therefore, the pedals 10 and the cleats 50 can be quickly and easily coupled and released by simply rotating the heel in both directions.
In addition, since the pedal engaging portion 23 is provided at a position connecting the vertices of the polygon T, when the pedal 10 is pedaled, two forces of pushing the pedal 10 downward and pulling it upward ( longitudinal force) can be stably transmitted between the cleat 50 and the pedal 10. That is, when the shoe SH is placed on the pedal 10 and moved up and down, the load may fluctuate in the front, back, left, and right directions due to various conditions such as vibration and inclination. Since the load is not dimensional but is provided two-dimensionally at the positions connecting the vertices of the polygon T, even if the load is about to shake, the load can be supported two-dimensionally from the position of the vertices of the polygon T. Directional force can be transmitted stably.
In addition, since the rotation axis N passes through the inner area T1 of the polygon T, the load can be supported from the position of the apex of the polygon T around the rotation axis N, and the force in the vertical direction can be more stabilized. can be conveyed clearly.
In addition, since the distance dimension L3 between at least two or more pedal engaging portions 23 and the rotation axis N is the same, two forces of pushing the pedal 10 downward and pulling it upward can be eliminated. More stable transmission is possible between the cleat 50 and the pedal 10.例文帳に追加
Further, since the distance dimension L3 between the pedal engaging portion 23 and the rotation axis N is all the same, the force of pushing the pedal 10 downward and the force of pulling it upward can be applied to the cleat 50 and the pedal. 10 can be transmitted more stably.
Further, since the pedal engaging portion 23 includes the pedal engaging wall portion 232 and the pedal engaging claw portion 231, the pedal engaging portion 23 and the cleat engagement portion 53 can be quickly and easily engaged and disengaged.

Further, since the pedal hole portion 211 is formed in the vicinity of the pedal engaging claw portion 231, foreign matter such as dust can be removed from the engaging space K, and the pedal engaging portion 23 and the cleat engaging portion 53 are separated from each other. can be quickly and easily engaged and disengaged, and it is possible to suppress deterioration of the fitting feeling at the time of engagement due to foreign matter. Furthermore, cleaning of the inner surface 236 of the pedal engaging claw portion 231 and the inner peripheral surface 238 of the pedal engaging wall portion 232 can be facilitated through the pedal hole portion 211 . Furthermore, even when the binding 20 is heated and expands (expansion of atoms), for example, in the summertime, the green atoms in the hole expand toward the hole due to the pedal hole portion 211 being formed. Since it cannot, it can grow only toward the outside of the pore. Therefore, even if the pedal hole portion 211 becomes larger, it is suppressed from becoming smaller (deformation is suppressed). can be quickly and easily engaged and disengaged. Furthermore, the weight of the pedal 10 can be reduced by the pedal hole portion 211 .

In addition, since the pedal engaging claw portion 231 and the pedal hole portion 211 have the same shape and are provided at positions facing each other, the foreign matter attached to the inner surface 236 of the pedal engaging claw portion 231 can be effectively removed from the hole having the same shape. It can be discharged naturally. Furthermore, in order to prevent expansion of the pedal engaging claw portion 231 and the engaging space K due to heat, heat can be efficiently discharged from the pedal hole portion 211 having the same shape.
In addition, since the area of the inner surface 236 of the pedal engaging claw portion 231 is smaller than the opening area of the pedal hole portion 211, the foreign matter adhering to the inner surface 236 of the pedal engaging claw portion 231 can be efficiently removed from the large hole of the same shape. Not only can it be naturally discharged well, but also the heat can be efficiently discarded.

Further, since the pedal engaging claw portion 231 has a circular shape and the pedal engaging wall portion 232 has an arc shape, the engaging space K can be circular in plan view. By inserting the circular cleat engaging claw portion 531 all the way in, the joint area between the outer surface of the cleat engaging claw portion 531 and the inner surface 236 of the pedal engaging claw portion 231 can be increased. Therefore, when the pedal 10 is pedaled, two forces (vertical force), ie, the force pushing the pedal 10 downward and the force pulling the pedal 10 upward can be efficiently transmitted between the cleat 50 and the pedal 10 . In the present embodiment, mainly the pedal rotation connection portion 22 and the cleat rotation connection portion 52 efficiently transmit the downward pressing force of the foot, and the pedal engaging portion 23 and the cleat engaging portion 53 efficiently transmit the upward pulling force. I can tell you well.
Further, since the pedal base portion 21 and the pedal engaging portion 23 have the same shape as the cleat base portion 51 and the cleat engaging portion 53, respectively, the binding 20 can also be used as the cleat 50, and the cleat 50 can be used as the binding. 20 can also be used. Therefore, not only can the manufacturing cost be reduced, but also the convenience in repair/replacement and storage can be improved.
In addition, since the shape and number of installation of the pedal engagement portion 23 are the same as the shape and number of installation of the cleat engagement portion 53, the manufacturing cost can be reduced with a simple configuration.

Further, since the outermost edge portion 234 of the pedal engaging portion 23 is one point, the pedal base portion 21 and the pedal engaging portion 23 and the cleat base portion 51 and the cleat engaging portion 53 have the same shape. Also, the pedal engagement pawl portion 231 and the cleat engagement pawl portion 531 can be moved into the engagement space K, respectively, and the pedal engagement portion 23 and the cleat engagement portion 53 can be quickly and easily engaged and released. be able to. That is, as shown in FIG. 6, for example, when the claw portion E is formed in a rectangular shape toward the center point P, the outermost edge portion 234 becomes two points, and at this time, the outermost circular arc locus R1 is the outermost edge. Between the two points of the portion 234, it protrudes radially outward from the claw portion E, and when the claw portions E are engaged with each other, the engaging wall portion E1 of the claw portion E and the claw portion E of the other side is separated. Because it collides with it, it can not penetrate to the back and the overlapping area is reduced. However, since the outermost edge portion 234 of the pedal engaging portion 23 is one point, when the pedal engaging portion 23 and the cleat engaging portion 53 rotate relative to each other, the outermost circular arc locus R1 protrudes radially outward. Therefore, the pedal engaging claw portion 231 and the cleat engaging claw portion 531 can be inserted all the way in, and the overlapping area between the pedal engaging portion 23 and the cleat engaging portion 53 can be increased. Therefore, the engaging force between the two can be increased. Further, since the innermost edge portion 235 of the pedal engaging portion 23 is one point, the pedal base portion 21 and the pedal engaging portion 23 and the cleat base portion 51 and the cleat engaging portion 53 have the same shape. Similarly to the above, the overlapping area between the pedal engaging portion 23 and the cleat engaging portion 53 can be increased, and the engagement force between the two can be increased.

In addition, since the pedal rotation connection portion 22 can rotate relative to the cleat rotation connection portion 52 while being magnetically attracted to the cleat rotation connection portion 52, the driver can put the shoe SH on or take it off from the pedal 10. The pedal 10 and the cleat 50 can be easily connected and disconnected only by doing so.
Further, since the pedal rotation connection part 22 includes the pedal rotation connection magnet part 222, the pedal 10 and the cleat 50 can be easily connected and released by simply putting the shoe SH on or off the pedal 10 by the driver. be able to.
Further, since the pedal rotation connection magnet portion 222 is made of a disc-shaped magnet and the area of the pedal joint surface 223 is the same as the area of the cleat joint surface 523, the driver can simply put the shoe SH on the pedal 10 and the pedal 10 can be moved. Even if the rotation axes N of the pedal rotation connection magnet portion 222 and the cleat rotation connection magnet portion 522 are not consciously aligned, they can be easily aligned and connected.
Further, since a plurality of pedal engaging portions 23 are provided at equal intervals in the circumferential direction S with the rotation axis N as the rotation center, the pedal engaging portions 23 and the cleat engaging portions 53 are arranged in the circumferential direction S. Engagement can be stably performed in a well-balanced manner, and two forces, that is, a downward pushing force and an upward pulling force on the pedal 10 can be efficiently transmitted between the cleat 50 and the pedal 10 in a well-balanced manner.
Further, since the pedal engaging claw portion 231 extends parallel to the pedal base portion 21 when viewed from the side, the pedal engaging portion 23 and the cleat engaging portion 53 can be quickly and easily engaged. can be released.

Further, according to the cleat 50, the same effects as those of the pedal 10 can be obtained.
Further, according to the pedal system 3, since the pedals 10 and the cleats 50 are provided, the pedals 10 and the cleats 50 can be quickly and easily engaged and disengaged.
Further, according to the bicycle 1, since the bicycle 1 is provided with the pedals 10 and the bicycle body 2, when the rider sits on the saddle 2d and grips the handlebars 2b, the pedals can be moved by simply turning the heel. 10 and cleat 50 can be quickly and easily engaged, and both can be quickly and easily released when stopping. Therefore, the driver can drive comfortably.

It can penetrate and strengthen the engagement force.
In addition, although the length dimension of the pedal engaging wall portion 232 in the circumferential direction S is half or less of the circumference of the pedal engaging claw portion 231, it is not limited to this and can may exceed Further, it is assumed that the pedal engaging wall portion 232 extends in the engagement direction S1 side area between the outermost edge portion 234 and the innermost edge portion 235 of the peripheral edge portion of the pedal engaging claw portion 231. However, it is not limited to this, and may extend beyond the space between the outermost edge portion 234 and the innermost edge portion 235 to the region on the release direction S2 side.
Further, although the pedal base portion 21, the pedal engaging wall portion 232 and the pedal engaging claw portion 231 are integrally formed, they are not limited to this and may be attached as separate members.
Also, although the pedal base portion 21 is made of metal, the material is not limited to this, and the material can be appropriately changed, for example, resin.

Further, at least one of the pedal recess 221 and the cleat recess 521 may not be provided and may be a flat surface or the like.
Further, although the pedal rotation connection magnet portion 222 and the cleat rotation connection magnet portion 522 are assumed to be circular, they are not limited to this, and their configurations can be changed as appropriate.
Note that the attraction means not only that the pedal rotation connection magnet portion 222 and the cleat rotation connection magnet portion 522 are directly joined together, but also that they may be joined indirectly through an intervening member such as a protective member. It may be in a state of attracting each other depending on the joint shape.
In addition, the pedal rotation connection magnet portion 222 and the cleat rotation connection magnet portion 522 are made of disk-shaped magnets, and the pedal contact surface 223 of the pedal rotation connection magnet portion 222 is the area of the cleat connection surface 523 of the cleat rotation connection magnet portion 522. , but not limited to this, and their configurations can be changed as appropriate.

It goes without saying that the cleat 50 can also be modified in various ways similar to the above.
Also, the configuration of the bicycle main body 2 can be changed as appropriate. For example, although the bicycle main body 2 is a two-wheeled vehicle having a front wheel 2c and a rear wheel 2e, it may be a three-wheeled vehicle or a four-wheeled vehicle.

Also, the configuration of the pedal system 3 can be modified in various ways.
FIG. 14 shows the pedal system 3B.
Pedal system 3B includes pedals 10B and cleats 50B. The pedal 10B has a binding 20B.
The pedal base portion 21 is made of a material such as iron that can be attracted by magnetic force. . A pedal stopper member 225 extending radially inward is provided at the edge of the pedal recess 221 . The pedal stopper member 225 is formed in a ring shape and provided concentrically with the pedal recess 221 at the edge of the pedal recess 221 . The diameter of the pedal stopper member 225 is smaller than the diameter of the edge of the pedal recess 221 . Furthermore, the height dimension from the edge portion of the pedal stopper member 225 to the bottom surface of the pedal recessed portion 221 is larger than the thickness dimension of the pedal rotation connecting magnet portion 222 .
Therefore, the pedal rotation connection magnet portion 222 is movable in the direction of the rotation axis N, and the pedal stopper member 225 contacts the pedal rotation connection magnet portion 222 so that the pedal rotation connection magnet portion 222 moves along the rotation axis N. It restricts movement outward.
Since the cleat 50B has the same configuration as the binding 20B, the description thereof will be omitted. Reference numeral 525 indicates a cleat stopper member.

With this configuration, when the binding 20B and the cleat 50B are separated from each other, the pedal rotation connection magnet portion 222 is attracted to the bottom portion of the pedal recess 221 by magnetic force, and the cleat rotation connection magnet portion 522 is attached to the cleat recess 521. It is attracted to the bottom surface by magnetic force. Then, when the driver places the shoe SH on the pedal 10B, the pedal rotation connection magnet portion 222 and the cleat rotation connection magnet portion 522 are attracted to each other by magnetic force, and move away from their bottoms and approach each other. The pedal rotation connection magnet portion 222 and the cleat rotation connection magnet portion 522 are attracted and joined together by magnetic force. Further, in the same manner as described above, when the rider rotates the heel, the pedal engaging portion 23 and the cleat engaging portion 53 are engaged. On the other hand, the driver rotates the heel in the opposite direction to release the engagement between the pedal engaging portion 23 and the cleat engaging portion 53, slide the shoe SH in the direction intersecting the rotation axis N, or lift the heel. Then, the pedal rotation connection magnet portion 222 and the cleat rotation connection magnet portion 522 come into contact with the pedal stopper member 225 and the cleat stopper member 525, respectively, and are separated from each other by being restricted in movement. Then, the pedal rotation connection magnet portion 222 and the cleat rotation connection magnet portion 522 are each attracted to the bottom surface by magnetic force. This releases the connection between the pedal 10B and the cleat 50B.

Accordingly, not only can the same effects as described above be obtained, but also the pedal rotation connection magnet portion 222 and the cleat rotation connection magnet portion 522 can be protected. That is, in a state in which the pedal 10B and the cleat 50B are not connected, the pedal rotation connection magnet portion 222 and the cleat rotation connection magnet portion 522 are attracted to the bottom surface, respectively, so that they do not protrude from the pedal base portion 21 and the cleat base portion 51. can be made Therefore, even if the user walks on the ground wearing the shoes SH with the cleats 50B attached, or puts the shoes SH on the pedals 10B without the cleats 50B, the pedal rotation connection magnet portion 222 and the cleat rotation connection magnet portion 522 are not connected. can be protected.

Further, as shown in FIG. 15, the pedal recess 221 and the cleat recess 521 may be through holes. A pedal suction plate 226 and a cleat suction plate 526 that cover the pedal recess 221 and the cleat recess 521 are provided on the rear surfaces of the pedal base portion 21 and the cleat base portion 51, respectively. The pedal attracting plate 226 and the cleat attracting plate 526 are made of a material that can be attracted by magnetic force, such as iron, and are formed in a plate shape.
As a result, the pedal rotation connection magnet portion 222 and the cleat rotation connection magnet portion 522 can be moved in the direction of the rotation axis N, and the same effect as described above can be achieved.
14 and 15, the pedal stopper member 225 and the cleat stopper member 525 are formed in a ring shape. For example, a plurality of members may be provided in the circumferential direction, or polygons such as triangles and squares, ellipses, and other shapes may be used.
Further, although the pedal stopper member 225 and the cleat stopper member 525 are provided in FIGS. 14 and 15, they are not limited to this, and may be provided on at least one of the pedal 10B and the cleat 50B.

The engaged state with the engaging portion 53 is maintained. That is, when the pedal engaging portion 23 and the cleat engaging portion 53 are engaged with each other, the pedal fixing projection 241 and the cleat fixing recess 541 are engaged with each other, and the pedal engaging portion 23 and the cleat engaging portion 53 are circumferentially fitted. Restrict movement in direction S. When the cleat 50 is rotated with a force equal to or greater than a predetermined force, the uneven engagement between the pedal fixing projection 241 and the cleat fixing recess 541 is released, and both can be moved in the circumferential direction S.
Accordingly, it is possible to prevent loosening of the engagement between the pedal engaging portion 23 and the cleat engaging portion 53 .

Although the pedal engagement fixing portion 24 and the cleat engagement fixing portion 54 are provided with the pedal fixing projection 241 and the cleat fixing recess 541, respectively, the configuration is not limited to this and can be changed as appropriate.

18, three pedal engaging portions and three cleat engaging portions are provided at equal intervals in the circumferential direction S, respectively.

Also, although the height dimension of the pedal engaging wall portion 232 is the same as the thickness dimension of the pedal engaging claw portion 231, it is not limited to this and can be changed as appropriate. For example, the height dimension of the pedal engagement wall portion 232 may be larger than the thickness dimension of the pedal engagement claw portion 231 . That is, the height dimension of the engagement space K may be set to be equal to or larger than the thickness dimension of the pedal engagement claw portion 231 .

Also, as shown in FIG. 19, the pedal system 3E may include pedals 10E and cleats 50E. The outer edge of the pedal base portion 21 is notched. That is, the pedal base portion 21 is formed by notching its outer edge together with the pedal hole portion 211 . The pedal hole portion 211 is provided at a position facing the engaging claw portion 231 in the thickness direction. Thus, the pedal hole portion 211 may have an edge portion extending over the entire circumference as shown in FIG. 7, or may be partially cut out as shown in FIG. This pedal hole portion 211 can prevent deformation of the cleat 50E and the binding 20E as much as possible, and can reduce weight.
A through hole is provided in the central portion of the pedal rotation connection magnet portion 222, and is fixed via a screw.
Further, the pedal engaging wall portion 232 is raised in the crossing direction from the pedal base portion 21 . That is, the pedal engaging wall portion 232 is provided to be inclined with respect to the pedal base portion 21 when viewed from the side. A substantially semicircular pedal engaging claw portion 231 is provided at the tip of the pedal engaging wall portion 232 .
Needless to say, the structure of the cleat 50E is also the same.
Under such a configuration, when the cleat 50E is rotated in a state where the pedal rotation connection magnet portion 222 and the cleat rotation connection magnet portion 522 are magnetically connected, the pedal engaging portion 23 and the cleat are rotated as shown in FIG. The engaging portion 53 is engaged to connect the cleat 50E and the binding 20E. Further, when the cleat 50E is reversely rotated, the engagement between the pedal engaging portion 23 and the cleat engaging portion 53 is released.

The pedal base portion 21 is provided with three engaging portions 23F. The engagement portion 23F includes a pedal engagement pawl portion 231F that is linearly extended obliquely upward from the pedal base portion 21 as viewed from the side. The pedal engaging claw portion 231F is formed in a rectangular parallelepiped shape, but the shape is not limited to this and can be changed as appropriate. The outermost edge in the radial direction of the pedal engaging claw portion 231F is curved. However, this outermost edge may not be curved.
A pedal hole portion 211 is provided in the vicinity of the pedal engaging claw portion 231F in the pedal base portion 21 . The pedal hole portion 211 includes a facing region 211a that faces the pedal engaging claw portion 231F in the thickness direction, and a front region 211b arranged in front of the pedal engaging claw portion 231F in the circumferential direction S. That is, the pedal hole portion 211 extends from a facing region 211a facing the pedal engaging claw portion 231F to a forward region 211b.

A pedal engaging fixing portion 24F is provided on the pedal base portion 21 of the binding 20F. The pedal engaging fixing portion 24F includes a pedal fixing through hole 241F, a pedal fixing convex portion 242F, and a pedal fixing elastic portion 243F.
The pedal fixing through-hole 241</b>F is a circular through-hole formed in the pedal base portion 21 . The opening area of the pedal fixing through-hole 241F is large on the rear surface of the pedal base portion 21 and small on the front surface.
The pedal fixing protrusion 242F is formed in a spherical shape and is arranged from the rear surface of the pedal base portion 21 into the pedal fixing through hole 241F.
The pedal fixing elastic portion 243F is made of an elastic member, and biases the pedal fixing convex portion 242F from the rear surface of the pedal base portion 21 toward the front surface.
As a result, in the natural state, the upper portion of the pedal fixing projection 242F protrudes from the surface of the pedal base portion 21 due to the biasing force of the pedal fixing elastic portion 243F. , moves toward the rear side against the biasing force of the pedal fixing elastic portion 243F, and is retracted from the surface of the pedal base portion 21 into the pedal fixing through hole 241F.
Further, a mounting hole 213</b>F for mounting to the crank connecting shaft portion 30 is formed in the pedal base portion 21 .

Further, the cleat base portion 51 is provided with a cleat engaging portion 53F and a cleat hole portion 511 . Since the cleat engaging portion 53F and the cleat hole portion 511 have the same configuration as the pedal engaging portion 23F and the pedal hole portion 211F, description thereof will be omitted here. Reference numeral 531F indicates a cleat engaging claw portion, reference numeral 511a indicates a facing area, and reference numeral 511b indicates a front area.
A cleat rotation connecting portion 52</b>F is provided at the outer edge of the cleat base portion 51 . The cleat rotation connection portion 52F is provided with a cylindrical cleat rotation connection peripheral wall portion 522F. The inner periphery of the cleat rotation connection peripheral wall portion 522F is formed as a circular peripheral surface or a polyhedral surface. The inner diameter dimension of the cleat rotation connection peripheral wall portion 522F is set to be equal to or larger than the outer diameter dimension of the cleat base portion 51 .
Further, the cleat base portion 51 is provided with a cleat engaging fixing portion 54F. The cleat engaging fixing portion 54</b>F is a through hole formed in the cleat base portion 51 .
Further, the cleat base portion 51 is formed with an attachment hole 513F for attachment to the shoe SH.
Neither the pedal 10F nor the cleat 50F is provided with a rotary connecting magnet portion or the like.

With such a configuration, as shown in FIG. 23(A), when the cleat 50F is brought closer to the pedal 10F, the pedal base portion 21 is disposed within the cleat rotation connection peripheral wall portion 522F. At this time, the inner peripheral surface of the cleat rotation connection peripheral wall portion 522F guides the pedal base portion 21 so that the cleat 50F and the binding 20F are concentrically arranged. Thereby, the cleat 50F and the binding 20F are connected. Here, connection refers to placing the cleat 50F and the binding 20F in a state in which mutual rotation is guided such that the cleat engaging portion 53F and the pedal engaging portion 23F are engaged. That is, the cleat 50F and the binding 20F are guided to rotate about the rotation axis N as the center of rotation. Then, the driver rotates the cleat 50F inward. At this time, the inner peripheral surface of the cleat rotation connection peripheral wall portion 522F contacts the outer peripheral surface of the pedal base portion 21, thereby guiding the rotation of the cleat 50F and the binding 20 about the rotation axis N. The cleat engaging claw portion 531F is arranged in the front region 211b of the pedal hole portion 211, and the pedal engaging claw portion 231F is arranged in the front region 511b of the cleat hole portion 511. Further, when the cleat 50F is rotated inward, the cleat engaging pawl portion 531F enters the opposing region 211a of the pedal hole portion 211 as shown in FIG. The pedal engaging claw portion 231F enters the opposing region 511a of the cleat hole portion 511. As shown in FIG. The cleat engaging claw portion 531F and the pedal engaging claw portion 231F engage with each other while being elastically deformed.

At this time, the inner surface of the cleat base portion 51 and the surface of the pedal base portion 21 are in contact with each other. Also, at this time, the cleat engaging fixing portion 54F and the pedal fixing through-hole 241F are arranged at the same position. Therefore, the pedal fixing convex portion 242F is biased by the pedal fixing elastic portion 243F to protrude from the surface of the pedal base portion 21 through the pedal fixing through-hole 241F and arranged in the cleat engagement fixing portion 54F. Further, when the cleat 50F is reversely rotated, the engagement between the pedal engaging portion 23F and the cleat engaging portion 53F is released.
As a result, the cleat engaging pawl portion 531F and the pedal engaging pawl portion 231F can be engaged with each other while being elastically deformed, and the restoring force of the elastic deformation increases the engaging force even if the contact area between the two is reduced. be able to. Therefore, it is possible to reduce the stroke of the rotation operation for engagement and disengagement by the driver, thereby improving convenience.
Further, since the cleat engagement fixing portion 54F and the pedal engagement fixing portion 24F are provided, the cleat engagement pawl portion 531F and the pedal engagement pawl portion 231F can be fixed in an engaged state. It can be easily released by simply rotating the cleat 50F outward.

Note that the cleat 50F and the pedal 10F may be upside down. However, it is needless to say that if it is turned upside down, the right and left feet will be left and right reversed.
Also, the cleat rotation connection peripheral wall portion 522F may not be provided. In addition, the inner and outer shapes of the cleat rotation connection peripheral wall portion 522F can be changed as appropriate. For example, as shown in FIG. 24, the outer shape of the cleat rotation connection peripheral wall portion 522F1 may be rectangular in plan view, and may be formed in a cube. Further, the outer shape of the cleat rotation connection peripheral wall portion 522F1 may be formed into a cylindrical body.
At least one of the pedal 10F and the cleat 50F may be provided with a rotary connection magnet portion.
Also, the cleat engagement fixing portion 54F and the pedal engagement fixing portion 24F may not be provided.

Also, as shown in FIG. 25, the pedal system 3G may include pedals 10G and cleats 50G. These pedals 10G and cleats 50G have different shapes. These pedal systems 3G are shown for the left foot.
The binding 20G is obtained by turning the cleat 50F shown in FIG. 21 upside down and has the same main structure, so the description thereof is omitted here. However, the binding 20G is not provided with the cleat engagement fixing portion 54F. Reference numeral 23G indicates a pedal engagement portion, reference numeral 231G indicates a pedal engagement pawl portion, reference numeral 22G indicates a pedal rotation connection portion, and reference numeral 222G indicates a pedal rotation connection peripheral wall portion. The pedal rotation connection peripheral wall portion 222G has the same configuration as the cleat rotation connection peripheral wall portion 522F.
The cleat 50G has a disk-shaped cleat base portion 51G. Three cleat engaging portions 53G are provided at equal intervals in the circumferential direction on the outer peripheral surface of the cleat base portion 51G. A front region 511b of the cleat hole portion 511 is formed between the cleat engaging portions 53G in the circumferential direction. The cleat engaging portion 53G has a cleat engaging pawl portion 531G. The cleat engaging claw portion 531G is formed as an inclined surface whose thickness gradually decreases toward the front in the circumferential direction at the front end portion in the circumferential direction of the cleat engaging portion 53G. The lower surface of the cleat engaging claw portion 531G is flat from the rear end portion to the front end portion in the circumferential direction.
The cleat 50G also includes a cleat engagement fixing portion 54G. The cleat engaging fixing portion 54G is formed in a disk shape and is attached to the cleat base portion 51G.
A cleat fixing notch 541G linearly extending from the edge to the inner region is formed in the cleat engagement fixing portion 54G. Three cleat fixing notches 541G are formed at equal intervals in the circumferential direction.

With such a configuration, when the driver places his/her foot on the pedal 10G, the cleat 50G is guided by the inner peripheral surface of the pedal rotation connection peripheral wall portion 222G and arranged concentrically within the pedal rotation connection peripheral wall portion 222G. Cleat 50G and binding 20G are connected. That is, the cleat 50G and the binding 20G are guided to rotate about the rotation axis N as the center of rotation. When the driver rotates the heel inward, the cleat 50G is guided by the inner peripheral surface of the pedal rotation connection peripheral wall portion 222G to rotate about the rotation axis N, and the cleat engaging claw portion 531G and the pedal engaging claw portion 531G rotate. The portion 231G engages while elastically deforming. At this time, the distal end portion of the pedal engaging claw portion 231G is arranged in the cleat fixing notch portion 541G, thereby fixing the engagement between the pedal engaging claw portion 231G and the cleat engaging claw portion 531G.
When the driver rotates the heel outward, the engagement between the pedal engaging claw portion 231G and the cleat engaging claw portion 531G is released.
Thereby, there can exist an effect similar to the above-mentioned.
Further, since the cleat engaging fixing portion 54G is provided, the cleat engaging pawl portion 531G and the pedal engaging pawl portion 231G can be fixed in an engaged state to rotate the cleat 50G outward. You can easily remove it.

Note that the cleat 50G and the pedal 10G may be upside down. However, it is needless to say that if it is turned upside down, the right and left feet will be left and right reversed.
Also, the pedal rotation connection peripheral wall portion 222G may not be provided. In addition, the inner and outer shapes of the pedal rotation connection peripheral wall portion 222G can be changed as appropriate.
At least one of the pedal 10G and the cleat 50G may be provided with a rotary connection magnet portion.
Further, it goes without saying that the number of cleat engaging portions 53G and cleat fixing notch portions 541G to be provided can be changed as appropriate.
Also, the cleat engagement fixing portion 54G may not be provided.
Also, the configuration of the cleat fixing cutout portion 541G can be changed as appropriate. For example, as shown in FIG. 26, the cleat engaging fixing portion 54G may not be notched, but may be a downward protrusion linearly extending from the edge of the cleat engaging fixing portion 54G to the inner region. That is, the cleat fixing lower protrusion 5411G may be formed on the cleat engagement fixing portion 54G. The cleat fixing lower convex portion 5411G protrudes downward in an arc shape from the back surface of the cleat engaging fixing portion 54G. As a result, when the cleat engagement pawl portion 531G engages with the pedal engagement pawl portion 231G, the distal end of the pedal engagement pawl portion 231G is disposed at a position overcoming the cleat engagement lower convex portion 5411G in the circumferential direction, thereby engaging the cleat. It is fixed in a state where the matching pawl portion 531G and the pedal engaging pawl portion 231G are engaged with each other. Of course, it goes without saying that the engagement is released by rotating the cleat 50G outward.

24 and 25, the pedal engaging portion 23 and the cleat engaging portion 53 engage in the engagement direction S1 and release in the release direction S2. For the left foot, the pedal engaging portion 23 and the cleat engaging portion 53 are modified so that the engaging direction S1 and the releasing direction S2 are opposite to each other. It goes without saying that
Further, by rotating the heel outward, the pedal engaging portion 23 and the cleat engaging portion 53 are engaged, and by rotating the heel inward, the pedal engaging portion 23 and the cleat engaging portion 53 are engaged. The orientations of the pedal engaging portion 23 and the cleat engaging portion 53 may be changed so as to release the .
