Abstract: This tool for recording the number of swings in a ball game includes a plurality of holed beads 20 and a cord 30 that is passed through the holes 20H of the beads 20 and that holds the beads 20 so that the beads 20 can slide, the cord 30 is formed from a cord material that does not stretch in an axial direction but that stretches in a diametrical direction and that is normally urged in a diameter-expanding direction, and the cord 30 constrict in diameter so as to elastically interlock with the walls of the holes 20H of the beads 20 and hold the beads 20 in position, whereby the beads do not shift even if a player strongly shakes the tool, the number of swings in the ball game can be reliably recorded and confirmed, and the tool is easily assembled.

Abstract: There is included a hooking cord 52 disposed on the back side of said finger insertion parts and held in and over at least three finger insertion parts 40C, 40D and 40E corresponding to a middle finger, a third finger and a little finger among the five finger insertion parts 40A through 40E of the glove body 10B so as to adjust a distance between the adjacent finger insertion parts whereby the three finger insertion parts can be pulled simultaneously by hooking the hooking cord 52 with a little finger of a hand not wearing the glove and grasping the finger insertion parts 40A and 40B corresponding the thumb and the first finger with a thumb and a first finger of the hand not wearing the glove 10.

Abstract: Although an accelerator interlocking member (26) and an acceleration function follow-up member (28) magnetically coupled with each other when an automobile stops or travels at a car speed less than a predetermined speed are released from the magnetic coupling when an accelerator erroneous operation is made, a normal operation security apparatus (100) serves to lock the accelerator interlocking member and the acceleration function follow-up member so that they are mechanically coupled whereby the accelerator interlocking member and the acceleration function follow-up member are integrally coupled with each other to prevent the release of the magnetic coupling of them on a normal operation so as to be enable to positively perform the overtaking operation and the ascent hill travel.

Abstract: A device for preventing an accelerator from being erroneously operated when an accelerator pedal of a motor vehicle is erroneously pushed down includes a magnetic coupling device comprising an accelerator interlocking member interlocking with an accelerator pedal and a throttle interlocking member connected to a throttle cable. When the accelerator pedal is pushed down during normal operation the throttle cable is operated through the magnetic coupling device to cause the motor vehicle to be accelerated. When the accelerator pedal (14) is erroneously pushed down in spite of the brake pedal being intended to be pushed down, the magnetic coupling device decouples and prevents the throttle valve from being operated and the motor vehicle from being accelerated.
