On the other hand, when removing the race shoe from the pedal, the race shoe is twisted in a horizontal plane. Then, the rear end projection (324) of the rotating cleat (32) (the rear end engagement portion (322)
8 is provided at a position deviated in the direction of the back surface of the paper of FIG. 8) from the concave end (214) (see FIG. 7) formed in the bent engagement piece (211) of the rear engagement body (21). The rear end protrusion (324) so that the rear engagement body (2

(26) is a rotating part between the inner and outer clamping bodies (12) and (13) and the pedal shaft (11), and two rotating parts of a rotating part of the central block (15) and the pedal shaft (11). Are connected via the rear engagement members (21) and (22) compared to the case where they are connected via more rotating parts.
The relative posture of the front engagement body (25) and the front engagement body (26) is unlikely to change flexibly, and the degree of freedom in changing the relative posture is low. Therefore, in this case, it is difficult to smoothly attach and detach the race shoes to and from the bicycle pedal.

く、クリート(32)の円滑な離脱が阻害される。The above problem will be described in more detail. In the above conventional device, the rear engagement body (21) rotates around only the pedal shaft (11). Therefore, the lowering distance of the bending engagement piece (211) at the time of attaching the cleat is larger than the case where the center of rotation is located, for example, below the rear end of the cleat (32). Few. That is, when the center of rotation of the rear engagement body (21) is located below the rear end bent part (322) of the cleat (32), the bent engagement piece (211) is used when the rear engagement body (21) is rotated.
Is almost horizontally moved back and forth and hardly descends. On the other hand, in the above-mentioned conventional one, the bending engagement piece of the rear engagement body (21) is used.
Since the lever (211) rotates about the pedal shaft (11), the descending amount of the bending engagement piece (211) is large. Therefore, when removing the cleat (32) in the above-mentioned conventional one, the bent engagement piece (211) of the rear engagement body (21) descends and this is
The rear end engaging portion (322) of the (32) is easily caught on the upper surface of the rear end engaging portion (322).

動中心のみを中心に回動するからである。On the other hand, when the center of rotation of the rear engaging member (21) is changed to a position near the rear end of the cleat (32) to solve the above problem, the center of rotation and the bending engagement piece (211) are changed. Is shorter than that of the conventional one, and a large force is required to rotate the rear engagement body (21) backward. In such a case, the cleat (32) cannot be smoothly attached or detached. This is because the bending engagement piece (211) rotates around only a single rotation center near the rear end of the cleat (32).

If the number of rotating parts existing in the path connecting (25) is small, the degree of freedom of change in the relative posture of the rear engagement body (21) and the front engagement body (25) decreases, and the cleat (32) Cannot be secured smoothly. The present invention has been made in view of the above points,
The rear engaging body (21) and the front engaging body (2
It is an object of the present invention to increase the degree of freedom in changing the relative posture of 5), thereby enabling the cleat (32) to be attached and detached more smoothly.

The relative attitude of the engagement piece (612) of the rear engagement body (61) with the engagement angle of the rectangular block (52) with respect to the pedal shaft (11) and the pedal frame (64) with respect to the pedal shaft (11) And the rotation angle of the rear engagement body (61) with respect to the pedal frame (64), the rotation angle of the rear engagement body (61) is determined by three types of rotation angles. Therefore, in the bicycle pedal according to the present embodiment, the front engagement body ( The relative posture change of the front engagement body (51) and the rear engagement body (61) by the number of the rotating parts existing in the path connecting the 51) and the rear engagement body (61),
That is, the degree of freedom of relative posture change between the U-shaped engaging portion (58) and the engaging piece (612) is increased. That is, the relative posture of the U-shaped engaging portion (58) and the engaging piece (612) changes flexibly. Accordingly, when the cleat (32) is engaged with the U-shaped engaging portion (58) and the engaging piece (612), the cleat (32) is engaged with the U-shaped engaging portion (58) and the engaging piece (612). ) May be slightly deviated from the proper position, the engaging pieces (612) may be engaged with the front and rear end engaging portions (32) of the cleat (32).
1) Engage smoothly with (322).

に引っ掛かる不都合が少なくなる。To remove the race shoe from the bicycle pedal, the race shoe is rotated slightly in a horizontal plane. Then, the vicinity of the tip of the cleat (32) shown by the imaginary line in FIG.
It comes into contact with the stopper (511) rising from (51). Also, with the rotation of the cleat (32), the rear end projection (324) of the rear end comes out of the arc-shaped recess (615) formed on the front edge of the front plate (614) of the engagement piece (612). , Whereby the rear engagement body (61) is rotated rearward. That is, the engagement piece (612) of the rear engagement body (61) and the U-shaped engagement section (5) of the front engagement body (51)
8) The interval is enlarged. When the race shoe is lifted in this state, the race shoe comes off the pedal. In this case, since the rear engagement body (61) rotates about the support shafts (69) and (69) positioned below the rear end of the cleat (32), the end plate (614) retreats in a substantially horizontal direction. I do. Therefore, the pedal shaft (1
The lowering amount of the end plate (614) is smaller than that of the above-mentioned conventional engaging projecting plate (211) which rotates only around 1), and therefore, the end plate (614) is Rear end engaging part (322)
The inconvenience of being caught on the surface is reduced.
