In this case, one end of an expansion member 3b of the expansion supporting member 3 is locked to a hook 2i of a support 2a, and the other end of the expansion member 3b is fixed to a leading end of an arm 3a. The expansion member 3b is contracted, and the arm 3a is turned, so that the arm 3a and the expansion member 3b can be housed in a storage box 5. COPYRIGHT: (C)2009,JPO&INPIT
