<P>PROBLEM TO BE SOLVED: To provide a syringe of a multi-space type which is manufactured at a low cost and shows excellent productivity. <P>SOLUTION: The syringe 10 is equipped with a cylindrical external cylinder 12, a pressing member 14 which is disposed to make close contact with an inner surface 12a of the external cylinder 12 and to slide on the inner surface 12a, and a stopper body 16. A protruding part 34 is provided on a main surface 16a of the stopper body 16 to make a top part 34a eccentric to the main surface 16a. A pressure from an opening end 18 applied to the stopper body 16 with the sliding movements of the pressing member 14 in a direction of an arrow A acts in a direction of an arrow B to deform the stopper body 16 in a state of making contact with a blocked end 20 to bend it. Consequently, a first gap 38 and a second gap 40 are formed between the inner surface 12a of the external cylinder 12 and the stopper body 16. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
