<p><P>PROBLEM TO BE SOLVED: To provide a joint structure for a toy capable of preventing the dropping-off of a sliding portion, with the number of parts decreased. <P>SOLUTION: The joint structure for a toy couples arms 61 to a front wheel chassis 5 rockable with each other, wherein a hemispherical first concave portion 61b, and a hemispherical second projecting portion 61c, formed mutually concentrically and having a same central axis in the vertical direction, are formed at each of the end portions 61a of the arms 61. The front wheel chassis 5 includes an upper front wheel chassis 52 formed with a hemispherical first projecting portion 52a complementary to the first concave portion 61b, and a lower front wheel chassis 51 formed with a hemispherical second concave portion 51a complementary to the second projecting portion 61c, wherein the upper front wheel chassis 52 and the lower front wheel chassis 51 nip the end portion 61a of the arm 61, with the first projecting portion 52a and the first concave portion 61b to be slid on each other, and with the second projecting portion 61c and the second concave portion 51a to be slid on each other. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
