Abstract
A hydraulic pressure cylinder with an integrated reservoir which includes a cylinder body of strengthened resin, a reservoir tank of strengthened resin molded with the cylinder body as one body and having a wall portion and an opening formed in the wall portion of the reservoir tank and having a frame portion defined by the opening, and a window plate formed of resin material soluble in said strengthened resin and having a high transparency characteristic, the window plate including a flange which is welded to an inner surface of a wall portion of a reservoir tank and a projecting part which projects from the flange toward an outer surface of the wall portion of the reservoir tank along the frame portion.
Claims3
A hydraulic pressure cylinder with an integrated reservoir, comprising:
- a cylinder body of strengthened resin;
- a reservoir tank of strengthened resin molded with said cylinder body as one body and having a wall portion, said tank having an opening formed in said wall portion of said reservoir tank so as to define a frame portion;
- a window plate formed of resin material soluble in said strengthened resin, separate from said reservoir tank, having a high transparency characteristic and a lower melting point than that of said reservoir tank, and being mounted on an inner surface of said reservoir tank, said window plate having a flange formed along an entire periphery of said window plate and a projecting part which projects from said flange toward an outer surface of said wall portion of said reservoir tank along said frame portion of said reservoir tank;
- and
- ultrasonic melt bonded connecting means for connecting said flange to said inner surface of said wall portion of said reseroir tank.
