    摘要： There is provided a constant-volume dispenser which allows easy and reliable air removal from a syringe. A constant-volume dispensing syringe 10 includes a syringe 12 and a constant-volume dispenser 14. The constant-volume dispenser 14 includes an outer cylinder 26 which extends in the Arrow A direction; an inner cylinder 28 and a spring 30 which are housed in the outer cylinder 26; and a lid member 32 which is fitted to the outer cylinder 26; a pusher 34 which penetrates the outer cylinder 26, the inner cylinder 28 and the lid member 32; and an operation member 36 which is attached to the outer cylinder 26. In a preparation operation, the operation member 36 is moved from an initial position to a stopping position whereas in operations after the preparation operation, the operation member 36 is moved from a stand-by position to the stopping position. Due to this arrangement, the travel distance of the pusher 34 in the preparation operation is longer than the travel distance of the pusher 34 after the preparation operation.
