UNIVERSAL JOINT MODULE AND HEAD MOUNT-TYPE DISPLAYING DEVICE

PROBLEM TO BE SOLVED: To provide a universal joint module including a base, a first support base, spherical rotational shaft, a fixing tool, and an elastic member, and a head mount-type displaying device.SOLUTION: A base includes: an inner space; a hole communicating with the inner space; and an opening communicating with the inner space and facing to the hole. A first support base is positioned in the inner space. A spherical rotational shaft includes a spherical head and a shaft body connected to the spherical head, the spherical head being rotationally positioned in the inner space and being in contact with the first support base, in which the shaft body penetrates the hole. A fixing tool is positioned near an opening in the inner space, and movably fixed to the base so as to adjust a distance between the fixing tool and the first support base. An elastic member is provided in the inner space so as to be positioned between the first support base and the fixing tool. The elastic member pushes the first support base by a pressure from the fixing tool to maintain the pressure between the first support base and the spherical head.SELECTED DRAWING: Figure 2 【課題】本発明は台座、第１支持台、球形回転軸、固定具及び弾性部材を含むユニバーサルジョイントモジュールを提供する。また、ヘッドマウント型表示装置を提供する。【解決手段】台座は内部空間、内部空間に連通する孔、及び内部空間に連通しかつ孔に対向する開口を含む。第１支持台は内部空間に位置する。球形回転軸は球頭部及び球頭部に接続される軸体を含み、球頭部が回転可能に内部空間に配置されかつ第１支持台に当接し、軸体が孔を貫通する。固定具は内部空間における開口の近くに位置し、かつ固定具は移動可能に台座に固定されて、固定具と第１支持台との間の距離を調整する。弾性部材は内部空間に配置されかつ第１支持台と固定具との間に位置し、弾性部材は固定具からの圧力により第１支持台を押して、第１支持台と球頭部との間の圧力を維持する。【選択図】図２
