Connecting mechanism

The utility model provides a connecting mechanism which can avoid excessive friction of a sliding surface of a guide piece and achieve light weight of the guide piece. The connection mechanism includes: a guide, one end of which is rotatably supported by a first member about a first axis, the guide extending in a direction orthogonal to the first axis; and a slider including a sliding portion supported by an outer peripheral portion of the guide, and a connecting portion extending from the sliding portion in a direction orthogonal to the extension direction and the first axis, in which the outer peripheral portion of the guide includes a plurality of circumferential surface portions and a plurality of flat surface portions, the guide plate is provided on the plurality of planar portions. 本实用新型提供一种连接机构，能够避免引导件的滑动面过度摩擦，且达成引导件的轻量化。连接机构包括：引导件，一端以第一轴线为中心可旋转地被第一部件支撑，所述引导件沿着正交于所述第一轴线的方向延伸；以及滑动件，包括滑动部与连结部，所述滑动部被所述引导件的外周部支撑，所述连结部从所述滑动部朝向与所述延伸方向以及所述第一轴线正交的方向延伸，其中所述引导件的所述外周部包括多个圆周面部以及多个平面部，引导板设置于所述多个平面部上。
