This power transmission device includes a motor, a worm connected to a rotating shaft of the motor, and a worm wheel engaged with the worm and disposed at an operation pedal side with respect to the worm, wherein a biasing member which biases the motor in a direction in which the worm and the worm wheel come in contact with each other when the motor is driven is disposed between the motor and a housing.

The invention relates to a control device with a stator unit fastened via a stator connection to a support body, and a rotor unit rotatable about the stator unit. The rotatability of the rotor unit about the stator unit can be influenced in a targeted manner by means of a braking device. For its rotatability about the stator unit, the rotor unit is mounted on the support body by means of at least one bearing unit of a bearing device, so that a force acting on the rotor unit from radially outside can be diverted via the bearing unit into the support body, bypassing the stator unit and the stator connection.

A device component has a magnetorheological brake device with a static holder and with two brake components. A first brake component is rotationally fixedly to the holder and extends in an axial direction. A second brake component has a hollow, rotary part which is rotatable about the first brake component. An encircling gap between the first and second brake components is filled with a magnetorheological medium. The first brake component has a core of magnetically conductive material which extends in the axial direction. An electrical coil is wound axially around the core and spans a coil plane. A magnetic field of the coil extends transversely through the first brake component. A maximum outer diameter of the electrical coil in a radial direction within the coil plane is greater than a minimum outer diameter of the core in a radial direction transversely to the coil plane.

An accelerator device includes at least one drive source, a pedal lever, and a power transmission mechanism. The pedal lever is configured to move according to a pedal depressing operation. The power transmission mechanism is configured to transmit force both in the pedal lever's closing direction and opening direction to the pedal lever by driving of the drive source.

An accelerator device includes a pedal lever, at least one drive source, a power transmission mechanism, and a locking mechanism. The pedal lever operates in response to a depressing operation. The drive source is configured to exert a reaction force as a force in a returning direction to the pedal lever. The power transmission mechanism transmits a drive force from the drive source to the pedal lever. The locking mechanism is capable of regulating the operation of the pedal lever.

An accelerator device includes an inner housing, a pedal lever, an urging member, and an actuator. The inner housing is supported to the outer housing by a support member. The pedal lever is rotatably supported to the inner housing in response to a stepping operation. The urging member urges the pedal lever in a closing direction. The actuator can drive the inner housing in an opening and closing directions of the pedal lever.

A knob assembly for a gas cooktop may include a knob configured to control a flow of gas from a burner of a cooktop starting at an off position, a knob mechanism arranged between the knob and the cooktop, the knob mechanism including a first part arranged below an underside of the knob, and a second part connected to the first part via a spring mechanism, where the first part is fixed to the knob and configured to rotate with the knob and the spring mechanism is configured to bias against the rotation.

A switch device includes an operating knob on which a tilting operation is performed, a detected portion that tilts with the tilting operation of the operating knob, a detection portion that detects movement of the detected portion, and a substrate on which the detection portion is arranged. The detection portion is aligned in an in-plane direction of the substrate and performs a switching operation upon detection of movement of the detected portion in the in-plane direction.
