    摘要: A neutral return mechanism includes an interlocking shaft to be pushed and pulled in an axial direction in conjunction with a swinging operation of an operation member; a housing member to support the interlocking shaft such that the interlocking shaft is movable in the axial direction and accommodate the interlocking shaft such that one of opposite end portions thereof protrudes; a neutral return spring to return the interlocking shaft from a post-movement position to an initial position, the neutral return spring being accommodated in the housing member such that the neutral return spring extends in the axial direction of the interlocking shaft, wherein the housing member includes a supported portion between a spring accommodation portion in which the neutral return spring is accommodated and a protrusion opening through which the interlocking shaft protrudes, the supported portion being supported at a bracket member.

    摘要: A passive haptic interface includes a first element which is rotatably movable about an axis or translatably movable along an axis, the first movable element rotating or moving opposite a second fixed element. The first movable element has a first plurality of magnetic poles spaced periodically at a pole pitch Ps and in the direction of movement, and the second fixed element has a second plurality of magnetic poles periodically spaced at a pole pitch Pr and in the direction of movement, where Ps and Pr are different numbers. A periodic stress is created by the magnetic interaction between the first movable element and the second fixed element in a period Pt. The pole pitches Ps and Pr are chosen such that Pt is strictly less than the smallest of the pitches Ps and Pr.

    摘要: A controller controls an operating device. The operating device includes an operating member capable of being pushed by an operator, a biasing unit biasing the operating member in a return direction, a detecting unit configured to detect a distance of movement of the operating member and output a detection signal indicating the distance of movement, and a braking unit configured to brake movement of the operating member. In response to determining, based on the detection signal, that the operating member is pushed into a predetermined retracted position, the controller causes the braking unit to hold the operating member pushed. In response to determining, based on the detection signal, that the operating member is moved in the return direction because of a clearance in a drive transmission system between the operating member and the braking unit, the controller causes the braking unit to stop holding the operating member.
