A gear drive device includes a first gear, a second gear that meshes with the first gear to allow torque transmission, and a biasing member that applies rotational torque in one direction to the first gear or the second gear. The first gear and the second gear are brought into contact at a contacting tooth surface thereof by the biasing member. At least one of the first gear and the second gear includes a non-contacting tooth surface that is on an opposite side of the contacting tooth surface and partially removed.

Gear drive device

A gear drive device includes a first gear, and a second gear that meshes with the first gear to allow torque transmission. At least one of the first gear and the second gear includes a fan-type gear. The first gear and the second gear each include a guide portion, and the guide portion is configured to position the first gear and the second gear in a gear rotation direction upon installation thereof.

An operating device includes a push operation mechanism that allows a push operation of an operation unit, a tactile feeling presenting unit including a drive transmission mechanism for presenting an operational feeling by driving the operation unit via the push operation mechanism, a detection unit that detects a motion of the operation unit, and a drive control unit that intermittently drives the operation unit by a drive control signal that is generated based on an activation pulse signal and an advance vibration pulse signal that includes a prescribed number of pulses and a voltage smaller than that of the activation pulse signal.

Push operation mechanism having tactile feedback

A vehicle wiper controller includes a wiper drive circuit which drives a wiper. An operation switch is manipulated in a plurality of manipulation directions or to a plurality of operation mode positions when a manipulation force is applied thereto. A wiper operation control unit electronically controls the operation of the wiper and sets the wiper to an operation mode corresponding to the manipulation of the operation switch. A control signal hold circuit, discrete from the wiper operation control unit, transmits a control signal to the wiper drive circuit when the operation switch is manipulated in a predetermined first manipulation direction or when the operation switch is manipulated to a predetermined first operation mode position. The control signal hold circuit sets a hold state for holding the transmission state of the control signal.

Wiper controller

A small click generating member is mounted on a yoke, and a large click generating member is rotatably mounted on an operating shaft. A plunger case is relatively rotatably mounted on the operating shaft, and large and small click pieces are mounted on the plunger case. An electromagnet is mounted on the yoke, and a plunger magnetic body attractable to the electromagnet is mounted on the plunger case. A magnet is mounted to cover the yoke. By changing over the supply of electricity to the electromagnet among a non-electricity-supply state, a backward connection electricity supply state and a forward connection electricity supply state, a generated coil magnetic field and a magnetic field of the magnet are applied in a cooperative manner, a magnetic circuit generated in the yoke can be changed over, and clicks are changed over among large click feeling, small click feeling and a fixed state.

Detent changeover switch apparatus

A control switch is equipped with a detent mechanism that generates a click feeling in a dial knob as a result of a detent piece of a plunger member gets over detent crests of a detent crest member. A stopper is provided in the plunger member, and the position of vertical motion of the stopper is switched by means of a rectilinear actuator, thereby switching rotational operation of the dial knob between an enabled state and a disabled state.

Control switch apparatus

A switch device that adjusts tactile sensation of a switch knob without control delay. The switch device includes a knob operated to switch an actuation state of an apparatus. A click mechanism is connected to the knob and includes a recess and a projection. Engagement of the projection and the recess provides a tactile sensation to a person operating the knob when the knob is operated. An adjustment mechanism generates a magnetic field to adjust tactile sensation of the click mechanism.

Switch device

A detent crest member is integrally rotatably mounted on a dial knob. On the other hand, on a peripheral surface of a plunger mounting member which is rotatably operated using a motor, a plurality of plunger members which generates clicks in a dial knob together with the detent crest member is mounted. In changing over click feeling, the motor is rotated thus selectively bringing one of the plunger members mounted on the plunger mounting member into resilient contact with concave/convex patterns of the detent crest member which form the pair with one plunger member.

A switch device including a switch operation shaft movable between a plurality of operation positions for setting a control amount for an apparatus. A follower is driven to follow the movement of the switch operation shaft. An attraction member generates magnetic force to attract the follower so that the follower becomes immovable and to hold the switch operation shaft at a single operation position.

A detent mechanism includes: a control member to be operated rotationally; a rotary member including a pair of magnetic poles adapted to rotate in conjunction with the control member; a plurality of electromagnets provided along a rotational path of the magnetic poles of the rotary member; and a detent controller that has a detent energization pattern in which a current energization direction and an energization amount are determined for the plurality of electromagnets. The detent controller gives a detent in operation of the control member by applying an electromagnetic force between at least one of the plurality of electromagnets and the rotary member by energization control for the plurality of electromagnets according to the detent energization pattern.

Detent mechanism

A portable device that resists deformation caused by an external force while remaining water resistant. The portable device includes a case, which is made of a flexible material. A battery compartment is formed in the case. A separable portion is arranged in the part of the case corresponding to the battery compartment. Part of the case is bent to open the separable portion and expose the battery compartment from the case.

Portable device having flexible case

A thin portable device having high strength. The portable device includes a portable device body for accommodating an electronic component used for communication. The portable device body includes an upper case and a lower case, each having a cavity. A holding frame holds peripheral portions of the upper case and the lower case so that the upper case and the lower case are connected to each other with the cavities opposed to each other.

Portable device having high strength

An engine switch device with improved convenience. The device starts and stops an engine. The device includes a key cylinder, which has a key slot, and a push button switch, which is pushed to stop or start the engine. The key slot is located in the center of the push button in a preferred embodiment.
