A work vehicle includes: a cab to be boarded by an operator, the cab including a roof; and a first antenna mounted on the roof. The first antenna is positioned selectively at one of a position lower than a topmost portion of the roof, and a position protruding upward relative to the topmost portion of the roof.

Work vehicle

A cab includes a dash panel disposed frontward of an operator's seat, and a monitor device disposed above the dash panel. The whole of the monitor device in the right-left direction overlaps a first front window when the monitor device is seen in the front-rear direction. The monitor device is disposed at a position at which the whole of the monitor device overlaps the first front window when the monitor device is seen in the front-rear direction.

There are provided a brake pedal sensor and a stop lamp lighting device in a vehicle, which are capable of controlling blinking of a stop lamp in a simple configuration. The brake pedal sensor includes: a stop lamp switching section which outputs a switch signal; a brake position sensor section which outputs a brake position signal; and a logic circuit section for receiving the switch signal and a blinking signal generated by the brake position signal are inputted, and which outputs a control signal for controlling lighting and blinking of the stop lamp. Using this brake pedal sensor allows configuration of the stop lamp lighting device in a simpler manner.

A rotation angle detecting device includes a rotating body rotating according to rotation of a vehicle pedal; a magnet attached to the rotating body; a magnetism detection element disposed facing the magnet at a predetermined interval from the magnet; and a first control circuit connected to the magnetism detection element. The center of the magnet is placed at the rotation center of the rotating body. The magnetism detection element detects magnetism of the magnet to output a detection signal. The first control circuit outputs an angle signal corresponding to a rotation angle of the rotating body according to the detection signal, and outputs a switching signal according to the rotation angle of the rotating body. The rotation angle detecting device reliably detects a rotation angle and turns a stop lamp on and off for example with a simple structure.

Rotation angle detecting device

A rotary-angle and rotary-torque sensing device includes a first rotator rotating together with a steering shaft, a second rotator rigidly mounted to the first rotator, a rotary torque sensor for sensing rotary torque generated between the first rotator and the second rotator, a first sensor rotating together with the first rotator, a second sensor rotating together with the second rotator, a rotary angle sensor for sensing rotary angles of the first sensor and the second sensor, and a controller for detecting rotary torque by using the rotary torque sensor and the rotary angle sensor.

The operator's cabis provided with a floor framehaving an opening for maintenancelocated at a floor baseand a lid bodyfor closing the opening for maintenance. The lid bodyincludes an upper inspection coverand a lower inspection coverwhich are aligned in a vertical direction with spacing so as to be attachable and detachable relative to the opening for maintenance. Disposed in a space between the upper inspection coverand the lower inspection coveris a floor ductthat can be disassembled and is provided for circulating supply air sent from an air conditioner

Operator's cab for a work vehicle

There is provided a rotary torque detecting device in which a first magnetic body and a second magnetic body are formed in substantially band shapes and third magnetic bodies are formed in substantially rectangular shapes, respectively, by forming the first magnetic body and the second magnetic body in the substantially band shapes and arranging the plurality of substantially rectangular third magnetic bodies at predetermined intervals between the first magnetic body and the second magnetic body, and the magnets. With this structure, in the rotary torque detecting device mainly used for detection of rotary torque of a steering of an automobile, it is possible to reliably detect the rotary torque at low cost.

Rotary torque detecting device

A sampling material for a carbonyl compound in a gas comprising a reagent capable of converting a carbonyl compound to a derivative thereof supported on a cation exchanger; and a sampling cartridge for a carbonyl compound in a gas wherein a sampling material for a carbonyl compound in a gas comprising a reagent capable of converting a carbonyl compound to a derivative thereof supported on a cation exchanger is packed in a column are provided. The sampling cartridge can be used for analyzing a carbonyl compound such as formaldehyde with ease and at a high sensitivity and high accuracy, and has excellent storage stability.
