は、保持体１１に回転可能に保持される。 Now, to describe the case of making a toy needle bearing with length M, first, the holder 11 on the open end 14 side of the holding space 12 is cut, and the holder 11 on the closed end 13 side is made to have length M. Next, the needle 15 is cut to a length that matches the length of the holding space 12 of the holding body 11 having a length M and is placed into the holding space 12. At this time, the needle 15 is inserted against the protruding portions 16, 16 on the outer peripheral side of the holder 11 that protrude toward the holding space 12. On the other hand, in the present invention, the needle 15 can also be inserted into the holding space 12 from the open end 14a of the holding space 12. The needle 15 has a protruding portion 1 on the outer peripheral side.
6, 16 and the inner circumferential protruding portions 17, 17 prevent it from coming out. In this way, needle 15
is rotatably held by the holding body 11.
