Abstract

A fluid spray nozzle includes a first member that is configured to be fixed to a sensor or a mounted portion to which the sensor is mounted, and a second member that is fixed to the first member. The first member has a fluid inlet and a first fluid passage that is connected to the fluid inlet. The second member has a second fluid passage that is connected to the first fluid passage, and a spray port from which the fluid that has passed through the second fluid passage is sprayed onto a predetermined location of the sensor.

First claim

What is claimed is:

1 . A fluid spray nozzle comprising:
a first member that is configured to be fixed to a sensor or a mounted portion to which the sensor is mounted, the first member having a fluid inlet and a first fluid passage that is connected to the fluid inlet; and a second member that is fixed to the first member, the second member having a second fluid passage that is connected to the first fluid passage, and a spray port from which the fluid that has passed through the second fluid passage is sprayed onto a predetermined location of the sensor.

2 . The fluid spray nozzle according to claim 1 , wherein
the second fluid passage is curved.

3 . The fluid spray nozzle according to claim 1 , wherein
a first cross-sectional shape of a part of the second fluid passage that is connected to the first fluid passage is different from a second cross-sectional shape of the spray port.

4 . The fluid spray nozzle according to claim 3 , wherein
the first cross-sectional shape is a circular shape, and the second cross-sectional shape is a rectangular shape.

5 . The fluid spray nozzle according to claim 1 , wherein
one of the first and second members has an opening into which a projection of the other of the first and second members is inserted, and an engagement position between the projection and the opening constitutes a connection portion that interconnects the first fluid passage and the second fluid passage.

6 . The fluid spray nozzle according to claim 5 , further comprising:
a pair of member-to-member fastening screws that fasten the first member to the second member, wherein the second member has a pair of second member screw insertion holes through which the pair of member-to-member fastening screws are passed, the pair of second member screw insertion holes being provided in a surface of the second member in which the opening or the projection is provided.

7 . The fluid spray nozzle according to claim 1 , wherein
the first member has a sticking surface configured to be adhered to an outer surface of the sensor.

8 . The fluid spray nozzle according to claim 7 , wherein
the first member has a pressing portion that presses against the mounted portion in a predetermined direction when the first member is adhered to the sensor.

9 . The fluid spray nozzle according to claim 8 , wherein
the pressing portion is a first pressing portion that is cuttably provided, and the first member further has a second pressing portion that presses against the mounted portion in the predetermined direction when the first pressing portion is removed.

10 . The fluid spray nozzle according to claim 9 , wherein
the first pressing portion and the second pressing portion project in the predetermined direction from an opposing surface of the first member that faces the mounted portion in the predetermined direction, the first pressing portion has a thin portion thinner than other parts of the first pressing portion, and the thin portion is provided in a position closer to the opposing surface than an end of the second pressing portion in the predetermined direction.

11 . The fluid spray nozzle according to claim 8 , wherein
the sensor is a camera, and the predetermined direction is an optical axis direction of the camera.

12 . The fluid spray nozzle according to claim 1 , wherein
the first member is configured to be fastened to the mounted portion by a pair of external fastening screws, and the first member has a pair of first member screw insertion holes through which the pair of external fastening screws are passed.

13 . The fluid spray nozzle according to claim 6 , wherein
the first member has a pair of first member screw insertion holes to be coaxially disposed with the pair of second member screw insertion holes, and the pair of member-to-member fastening screws also fasten the first member to the mounted portion.

14 . An assembly comprising:
the fluid spray nozzle according to claim 1 ; and the sensor to which the fluid spray nozzle is fixed.

15 . The assembly according to claim 14 , wherein
the sensor is a camera, and the predetermined portion of the sensor is a lens of the camera.
