A vehicle display device pointer includes a translucent pointer that has a pointer main body disposed on a front side of a dial plate having a penetration hole and extending along the dial plate, a shaft protruding toward the penetration hole, and a light guide connecting the pointer main body and the shaft; a lightproof first shielding member that covers a proximal end portion of the pointer main body and the light guide from a front side and a lateral side; and a lightproof second shielding member that covers the proximal end portion of the pointer main body and the light guide from the back side. The pointer main body emits light by light emitted from a light source and incident on the shaft, and the second shielding member has protrusions that protrude toward the front side, and close gaps.

A gauge device is provided and includes an analog display to signify a measured valued, a motor and worm gear arrangement which is configured to retain a current state of the analog display when de-energized or to change the analog display when energized and a control system. The control system is configured to normally de-energize the motor and worm gear arrangement and to energize the motor and worm gear arrangement only in accordance with a calculated state of the analog display differing from the current state by at least a threshold level.

An illuminated pointer for a vehicle instrument cluster provides a more uniform light by propagating light from a source, through an elongate, light-transmitting prism formed to have multiple, inclined light-reflecting surfaces. Each surface being at a different angle, reflects light at a slightly different angle producing a corresponding number of refracted light maxima along the length of the prism. A more uniform refracted light is produced.

A display device for a vehicle includes: a dial plate having an indicator portion corresponding to vehicle information on a viewing side; an image display panel disposed on a back side of the dial plate opposite to the viewing side to luminescently display an image; and a light transmissive display plate that includes a reflective portion disposed on the viewing side of the dial plate to reflect a light from a light source to the viewing side. A region of the dial plate, which faces the image display panel, is set to have a light transmission property to transmit the image of the image display panel through the region of the dial plate.

A unique, wireless pressure or temperature transmitter apparatus that substitutes unnecessary transmission information with simplicity and efficiency. The battery powered device utilizes a pressure or temperature gauge with adjustable switch contacts to wirelessly transmit the electrical state of the switch contacts rather than a pressure or temperature value. This is used in an application where the measured value is not needed to be known, but rather, if the measured value has or has not reached a specific value.

A pointer including a pointer body constituted by a plate member, an engraved section provided in at least one of front and back surfaces of the pointer body excluding an edge of the pointer body, and a reinforcing section provided at the edge of the pointer body by the engraved section.
