Title:
ねじり回転関節機構及びロボットアーム機構
Document Type and Number:
Japanese Patent JP6773768
Kind Code:
B2
Abstract:
Provided is a torsional rotational joint mechanism that realizes simplification of a structure, reduction in weight, and falling-off prevention. The torsional rotational joint mechanism that is mounted to a robot arm mechanism includes a fixed section in a cylindrical shape, a motor unit that is housed in the fixed section, and a rotating section that is fixed to an output shaft 65 of the motor unit. A flange section in an annular shape is jutted out on an outer circumferential surface of a tip of the fixed section to project outward, and one or two or more falling-off prevention sections are attached to a rear end surface of the rotating section in such a manner that the flange section on the fixed section is sandwiched between the one or two or more falling-off prevention sections and the rear end surface of the rotating section.
