Reference numeral 03 denotes a hand member 10 according to the size of the prize 100 because the hand members 106 and 106 are integrally formed.
There is a problem that the opening and closing angles of the hand members 106 and 106 cannot be adjusted or the shapes of the hand members 106 and 106 cannot be changed according to the shape of the premium 100.

When the opening / closing angle is adjusted according to the small prize 100, the driving motor is subjected to a large load when the large prize 100 is gripped, the heating is performed, the hand member or the gear is damaged, and conversely, the prize is not held. There was a problem that would break. Therefore, in the prize acquisition game machine 101 using the conventional gripping device 103, there is a problem that the size and shape of the prize 100 housed therein are almost the same and lack interest.

きるという効果がある。As described above, the gripping device according to the present invention transmits the driving force of the driving means such as a driving motor to the hand member via the elastic member. It can be turned in the direction opposite to the driving direction of the driving means within the range of elastic deformation. Therefore, in the case of a prize larger than the prize normally grasped, the pair of hand members can be opened wider than usual within the range of elastic deformation of the elastic member to grasp the prize, and a large load is applied to a driving means such as a drive motor. Such an effect can be prevented, and furthermore, there is an effect that breakage of the hand member and the gear and breakage of the premium can be prevented. Further, since the hand member is configured to be freely bent by at least two members, there is also an effect that the shape of the hand member can be changed along the contour of the premium. Therefore, in the prize acquisition game machine equipped with the gripping device according to each claim of the present application, the size,
There is an effect that various premiums irrespective of the shape and the material can be accommodated.
