MODEL

PROBLEM TO BE SOLVED: To connect two parts relatively rotatably and in a manner surely capable of maintaining a post rotation state.SOLUTION: The model 101 includes: an arm part 104 having a rotary shaft 110; and a body part 103 that has a shaft support part 111 and that is relatively rotatably connected to the arm part 104. In the arm part 104, a projection 112 is prepared and, in the body part 103, a recess 113 is prepared which engages with the projection 112 as the rotary shaft 110 is inserted into the shaft support part 111. In the rotary shaft 110 and the shaft support part 111, there are installed engaging parts 121, 122 which engage with each other and which regulate movement in the axial direction of the rotary shaft 110 between the first position where the projection 112 fits in the recess 113 and the second position where the projection 112 comes out from the recess 113. 【課題】二つの部分を相対回動可能に且つ回動後の状態を確実に保持可能に連結する。【解決手段】模型１０１は、回動軸部１１０を有する腕部１０４と、軸支持部１１１を有し、腕部１０４に対して相対回動可能に連結される胴体部１０３と、を備え、腕部１０４には凸部１１２が設けられ、胴体部１０３には回動軸部１１０が軸支持部１１１に挿入されるのに伴い凸部１１２と嵌合する凹部１１３が設けられており、回動軸部１１０及び軸支持部１１１には、互いに係合し、凸部１１２が凹部１１３に嵌合する第１位置と凸部１１２が凹部１１３から脱する第２位置との間で回動軸部１１０の軸方向の移動を規制する係止部１２１，１２２がそれぞれ設けられている。【選択図】図２
