[ That is, when the driver desires to set the locking portion 51 to be kept in the locked state even if the driver freely uses the hand portion separated from the sensor portion 61 during pedaling, the driver turns the switch portion 63 ON . In this case, the rotation of the rear engaging portion 41 is restricted by the locking portion 51 irrespective of the operation of the sensor portion 61. At this time, the driver can twist the cleansing shoes 10 to the side so that the front protrusions 21 or the rear protrusions 23 of the cleat 20 can separate the coupling parts of the pedals, thereby separating the cleats shoes from the pedals.

If the driver desires to release the locking state of the locking portion 51 when the hand is separated from the sensor portion 61 during pedaling, the driver may turn the switch portion 63 to the OFF state. In this case, the rotation of the rear engaging portion 41 can be limited or restricted by the locking portion 51 in accordance with the operation signal of the sensor portion 61. [
