• This pin 33 retains the protru ⁇ sion 31 in position and prevents the whole rotatable thumb- grip 3 ' o to be slipped out from the slot 38 of the first handle member 1'. Accordingly, the rotatable thumb-grip 5 3o can be rotated from right side of the first handle mem ⁇ ber 1 ' as shown in Figure 3B to the left side as shown in Figure 3C and vice versa.
• ⁇ e flax portion 34 projects out as thickly as its thickness from the surface level of the first handle mem ⁇ ber 1' as shown in Figure 3D.

• the hand-grip structure with a fixed thumb-grip must be constructed in both handles of a skipping rope for the user's both hands. But if the hand-grip structure has o the rotatable thumb-grip 3o, one hand-grip structure is sufficient for the user to develop all the muscles of both hands.

At this time, the user pushes: the whole lower part of the spring 13B to the direction of arrow R as shown in Figure 6, and closes the two handle members 1* and 1 to each other. Thus, the spring 13B is slidden to the direction of arrow R and laid down in the first and . second recessed portions 23Aand 22A.

And further, as the normal shape of a conventional hand ⁇ grip is that of a diverged twig, it is very inconvenient and troublesome to carry along.
