## Abstract

An oil jet device for supplying pressure oil which is supplied from a pressure oil supply source, includes a valve body and a supporting portion. The valve body is molded by cold-forging a metal material and accommodates a valve portion for controlling the supply of the pressure oil from the pressure oil supply source. The supporting portion is molded by cold-forging a metal material, supports the valve body, and has a first principal surface having a flat shape and configured to abut on an attachment target object.

## Claims

### Claim 1

An oil jet device for supplying pressure oil which is supplied from a pressure oil supply source, the oil jet device comprising:
a valve body that is molded by cold-forging a metal material and accommodates a valve portion for controlling the supply of the pressure oil from the pressure oil supply source; and
a supporting portion that is molded by cold-forging a metal material, supports the valve body, and has a first principal surface having a flat shape and configured to abut on an attachment target object, wherein
the supporting portion has a planar shape, and includes a valve body supporting portion that supports the valve body and a bolt insertion portion in which a bolt is insertable, the supporting portion having a thickness in a thickness direction orthogonal to the first principal surface; and
the bolt insertion portion has a smaller thickness than the valve body supporting portion in the thickness direction, and a bolt insertion hole for insertion of the bolt is formed in the bolt insertion portion by cold-forging and penetrates through the bolt insertion portion in the thickness direction to open to the first principal surface,
wherein
the valve body supporting portion is formed with a valve body insertion hole in the thickness direction of the valve body supporting portion,
the valve body has a cylindrical shape, and has a supported portion that is press-fitted to the valve body insertion hole, and a projection portion connected to the supported portion to project toward a side where the pressure oil is supplied, from the first principal surface,
the supported portion has a smaller length in the thickness direction than the valve body supporting portion, and
the projection portion has a larger diameter than the supported portion, the supported portion and the projection portion define a step having a step surface, and the step surface is orthogonal to the thickness direction and is in contact with the first principal surface.

### Claim 2 (depends on 1)

The oil jet device according to claim 1, wherein
the supporting portion and the valve body are molded by cold-forging a carbon steel.
