Claims

[Scope of utility model registration request]

In a piston mechanism comprising a cylinder and a piston including a piston gasket that contacts an inner wall of the cylinder in an airtight manner, the piston includes a piston rod and a tip of the piston rod formed at a predetermined interval in the axial direction. upper and lower limit stopper members, and a disk-shaped packing that is supported movably in the axial direction between the upper and lower limit stopper members, and a predetermined axially extending outer circumference of the disk-shaped packing is provided. A piston mechanism applied to a compression type atomizer, etc., characterized in that at least two protrusions are provided in airtight contact with the inner wall of the cylinder at intervals, and a grease reservoir is provided between the protrusions.
