摘要： A gasket is capable of providing an excellent slidability and holding its sealability without applying lubricant and a gasket that can prevent a resin film from being peeled off of a gasket body and prevent the generation of a molding defect such as pinholes. The gasket can be installed slidably in a outer tube of a syringe, including a gasket body and a resin film formed of a material lower in coefficient of friction than a material of the gasket body, which covers at least an outer periphery of the gasket body, in which when a surface roughness of the resin film on the outer tube side is defined as Ra1 and a surface roughness of the resin film on the gasket body side is defined as Ra2, a relationship of 1.5 Ra1≦Ra2 is satisfied.

摘要： A syringe with which an accurate amount of a liquid can be discharged by a simple operation.The syringe 1 includes an outer tube 2, a gasket 3 slidable in the outer tube 2, a pusher 4 operable for moving the gasket 3, and a stopper 5 disposed to be slidable along the longitudinal direction of the pusher 4. The stopper 5 is fixed relative to the pusher 4 by the engagement of engaging portions, provided therein, with racks 47a, 47b formed on the pusher 4. When an operating portion 71 is depressed, the fixation condition is released, permitting regulation of the position of the stopper 5 on the pusher 4. When the depression on the operating portion 71 is canceled, the fixation condition is retained. When the pusher 4 is pressed in the tip end direction, a tip end face 66 of the stopper 5 comes into contact with a base end portion 28 of the outer tube 2, whereby the depth of insertion of the pusher 4 into the outer tube 2 is restricted, and a set amount of a chemical 100 is discharged through a diameter-reduced portion 22.
