Abstract
An optical unit includes an optical sensor, a nozzle and a fixing part. The nozzle is positioned and configured to eject fluid onto an optical surface of the optical sensor. The fixing part is slidably engaged over the optical sensor and the nozzle from a side of the optical sensor having the optical surface and integrally fixes the optical sensor and the nozzle to each other.
Claims9
An optical unit comprising:
- an optical sensor;
- a nozzle that is positioned and configured to eject fluid onto an optical surface of the optical sensor, the nozzle including an internal fluid flow channel and a fluid outlet that receives the fluid from the internal fluid flow channel and that ejects the fluid directly onto the optical surface of the optical sensor, the nozzle being fitted to an outer periphery of the optical sensor;
- and
- a holder that i) is a separate piece from the optical sensor and the nozzle and is movable relative to the optical sensor and the nozzle, including the fluid outlet of the nozzle, before being engaged with the optical sensor and the nozzle, ii) is slidably engaged over the optical sensor and the nozzle from a side of the optical sensor having the optical surface without coming between the optical sensor and the nozzle and iii) integrally fixes the optical sensor and the nozzle to each other.
