Hinge device and hinge device base

A hinge device base comprising a substrate having a substantially planar first face comprising a side facing away from a mounting surface, a first movable member provided on the first face capable of moving in a first direction along the first face with respect to the substrate, and a first position adjusting mechanism for adjusting a position of the first movable member in the first direction with respect to the substrate, with the first movable member removably connected either indirectly or directly to a body part that is rotatably connected to an attachment member;

• a shaft guiding recessed section and a fitting recessed section that extends from the shaft guiding recessed section, with both formed on the first face of the substrate;
• the shaft guiding recessed section and the fitting recessed section each having a front side edge and a back side edge spaced apart in a second direction orthogonal to the first direction along the first face;
• a substrate side guiding section is provided on the shaft guiding recessed section, and a first adjusting shaft is provided between the substrate and the first movable member, with the first adjusting shaft including a first shaft part that rotatably engages to the first movable member around a first rotation axis line orthogonal to the first face and is inserted into the shaft guiding recessed section so as to be guided in the first direction, and a first shaft-side guiding section which engages with the substrate side guiding section;
• and
• a fitting section located in the first movable member, and the fitting section is inserted into the fitting recessed section so as to be able to slide in the first direction.
