Abstract

A method of assembling a vehicle cleaner nozzle provided in a vicinity of a leading end of a piston accommodated to be movable forward and backward with respect to a cylinder so as to inject a cleaning medium on an object to be cleaned which is mounted on a vehicle includes: assembling a nozzle chip to a housing along a first direction so as to form a feedback flow path for swinging and injecting the cleaning medium by accommodating the nozzle chip in an interior of the housing; and assembling the housing in a state where the housing accommodates the nozzle chip to a holder supported by the piston along the first direction.

First claim

The invention claimed is:

1. A method of assembling a vehicle cleaner nozzle provided in a vicinity of a leading end of a piston accommodated to be movable forward and backward with respect to a cylinder so as to inject a cleaning medium on an object to be cleaned which is mounted on a vehicle, the method comprising:
assembling a nozzle chip to a housing along a first direction so as to form a feedback flow path for swinging and injecting the cleaning medium by accommodating the nozzle chip in an interior of the housing, and
assembling the housing in a state where the housing accommodates the nozzle chip to a holder supported by the piston along the first direction so that the nozzle chip is sandwiched between the housing and the holder along the first direction.

2. A method of assembling a vehicle cleaner nozzle for injecting a cleaning medium on an object to be cleaned that is mounted on a vehicle, comprising:
providing a nozzle chip having a pair of protruding portions that form an oscillation space therebetween,
providing a housing having a first inner wall and a second inner wall that form a first opening portion,
assembling the nozzle chip in the opening porting of the housing along a first direction so as to form a feedback flow path surrounded by the first inner wall and the second inner wall of the housing and each of the pair of protruding portions of the nozzle chip, and
assembling the housing in a state where the housing accommodates the nozzle chip to a holder supported by a piston along the first direction.
