A washer nozzle comprises: a nozzle connecting portion to which a hose, that supplies a washing liquid, is connected; a nozzle main body portion that has, at an interior thereof, a flow path that communicates with an interior of the nozzle connecting portion and that has a jetting hole that opens toward an exterior at one end side of the nozzle main body portion, the nozzle main body portion jetting the washing liquid out toward a windshield glass of a vehicle from the jetting hole; and a water repellent portion that, at at least a portion of the flow path, structures an inner peripheral surface that extends to the jetting hole, and that is formed of a material that is water repellent.

Washer nozzle, wiper arm equipped with nozzle, and vehicle wiper device

A wiper device includes: a pivot shaft that rotates back and forth within a predetermined angular range; an arm head that is fixed to the pivot shaft; a cover that is mounted to the arm head; and a wiper arm that is pivotally supported on the arm head to come into and out of contact with a surface to be wiped. The wiper arm includes an engagement concave portion that extends in a longitudinal direction of the wiper arm at a side portion in a pivot direction of the wiper arm. The cover includes an engagement convex portion that extends in the longitudinal direction of the wiper arm. Relative movement of the wiper arm and the cover is restricted by engagement between an engagement wall portion of the engagement concave portion and the engagement convex portion.

Wiper device

An input disk and a clutch disk are supported by an output shaft in such a manner that the input disk is rotatable relative to the output shaft, and the clutch disk is non-rotatable relative to and is axially movable relative to the output shaft. When a large load torque is exerted about the output shaft, relative rotation between the input disk and the clutch disk occurs. A connecting rod has one end connected to a worm wheel, and is reciprocally swung through rotation of the worm wheel. A rotatable lever has one end, which is connected to the other end of the connecting rod, and has the other end, which is engaged with and is secured integrally with the gear teeth of the input disk.

Motor apparatus

A connector part extends outward of a yoke housing from a holder base and is connectable with an external connector to receive an electric signal. A contact base extends from the holder base into an interior of the gear housing through a communication hole, which is formed in a yoke housing side end of the gear housing. The contact base supports terminals, which provide an electrical connection between stationary contacts and brushes. An intermittent drive unit is installed to the connector part to intermittently drive an armature through the brushes based on the electric signal received from the external connector.

Wiper motor for driving wiper

In a forging process step, a small diameter portionis formed in the leading end portion of a cylindrical shaft material, and an installation depressed portionis formed on a base end face of the shaft materialfor installing a balltherein to receive thrust force, by cold forging process using a forging mold. In a worm forming process after the forging process step, a wormis formed in the small diameter portionby rolled dies. The small diameter portionand the installation depressed portionare formed by cold forging process, so that an outer circumferential face of the small diameter portionand an inner face of the installation depressed portionbecome even surfaces with small surface roughness.
