PROBLEM TO BE SOLVED: To provide a syringe, which cannot be bulky when packaged and is capable of adjusting a physical relationship between a finger rest member and a blade surface of a puncture needle by rotating the finger rest member.SOLUTION: The syringe includes an outer tube, and the finger rest member 4 rotatably set around an axis of the outer tube, a gasket capable of sliding in the outer tube, and a plunger to move and operate the gasket along the outer tube in an axis direction, which are provided on a base end part of the outer tube. The outer tube is composed of a bottomed cylindrical member, where an opened part with a reduced diameter in relation to a body section of the outer tube is integrally formed so as to project on the center part of a bottom section on an end. The finger rest member 4 has a body section 41 composed of a pair of platy parts oppositely projecting each other through a rotation axis of the finger rest member 4. A plurality of convex parts 43 are formed on an inner surface of the body section 41, and a plurality of projections 42 are formed in a vicinity of an opening 44 of a surface 45 on the end of the body section 41. |
