This patent was filed on September 1, 2020 and was published online on December 26, 2023.From the background information supplied by the inventors, news correspondents obtained the followingquote: “BACKGROUND ART“Manipulator devices used for a painting work are known, which are provided with a nozzle. The nozzlerotates with two degrees of freedom, and has a gear part which is sandwiched between two bevel gears andis disposed at a base body so as to mesh with the bevel gears (for example, see Patent Document 1).”Supplementing the background information on this patent, NewsRx reporters also obtained the inventors’summary information for this patent: “In order to solve the conventional problem, a joint structure fora robot according to the present disclosure includes a first link and a second link rotatably coupled to eachother via a joint part, and a first actuator and a second actuator. The joint part has a first rotary memberdisposed so that an axial center thereof is oriented in a first direction and connected to the first link, apair of second rotary members disposed so that an axial center thereof is oriented in a second directionperpendicular to the first direction, and so as to engage with the first rotary member, and a shaft memberhaving a first shank and a pair of second shanks. The first actuator transmits a rotational movementthereof to one of the second rotary members via a rotary transmitting member. The second actuatortransmits a rotational movement thereof to the other second rotary member via the rotary transmittingmember. The shaft member is formed so that the first shank is oriented in the first direction and the pairof second shanks are oriented in the second direction. The first rotary member is disposed so that thefirst shank of the shaft member is inserted therein. The pair of second rotary members are disposed sothat they oppose to each other and the second shank of the shaft member is inserted therein. The firstlink pivots relatively to the second link by the first actuator and the second actuator rotating. The jointstructure further includes a pressing member connected to the second shank and configured to press thesecond rotary member inwardly.
