Consisting of a tubular injection portion used to receive a shaft of said spent discarded injection portion releasably attached to one end of this casing and extending in a longitudinal direction on an extension of the axial axis, A free end having a handle on the opposite side of the injection portion is fitted with a cap or the like covering the end opposite to the injection portion of the casing and a resilient closure member adjacent to the cap is disposed; This closing member is located at the working position of the plunger rod. Two pressure coil springs (12, 15) surrounding the plunger rod and having different resilience in a form cooperating with the locking portion assigned to the plunger rod are slidably longitudinally within the casing (2). One end of one of the two joining coil springs 12 and 15 is supported by the cap 6 of the casing 2, and the other end thereof is supported by the plunger rod 8. It is supported by one spring support 11 slidably supported in the longitudinal direction by means of which one end of the other pressure coil spring 15 is supported by the one spring support 11 and the other end is A syringe characterized in that it is supported on the other spring bearing (10) fixed to the free end of the plunger rod (8) side of the injection portion (29). 제1항에 있어서 탄력이 강한쪽의 가압코일스프링(12)이 케이싱(2)의 캡(6)과 길이방향으로 접동가능한 한쪽의 스프링받이(11)와의 사이에 배치되어 있고 탄력이 약한쪽의 가압코일스프링(15)이 상기 길이방향으로 접동가능한 한쪽의 스프링받이(11)와 주사부분(29)쪽의 고정된 다른쪽의 스프링받이(10)와의 사이에 배치되어 있는 것을 특징으로 하는 주사기.The pressurized coil spring 12 of the strong side is arrange | positioned between the cap 6 of the casing 2, and the spring receiving part 11 which is slidable in a longitudinal direction, A syringe, characterized in that the pressure coil spring (15) is arranged between the spring bearing (11) slidable in the longitudinal direction and the other spring bearing (10) fixed to the injection portion (29). 제1항에 있어서 플런저로드(8)에 의해서 길이방향으로 접동가능하게 지시된 한쪽의 스프링받이(11)가 슬리브로서 형성되어 있고 이 슬리이브의 내경폭의 칫수가 플런저로드(8)의 외경(d)칫수와 거의 같은 것을 특징으로 하는 주사기.The spring bearing 11 is formed as a sleeve according to claim 1, which is slidable in the longitudinal direction by the plunger rod 8, and the dimension of the inner diameter width of the sleeve is the outer diameter of the plunger rod 8. d) a syringe, characterized in substantially the same as a dimension. 제3항에 있어서 직경이 큰쪽의 가압코일스프링(12)을 위한 스프링받이(11)로서의 슬리이브가 반경방향의 외측으로 돌출하는 환상칼라(13)를 가지고 있으며, 적어도 부분적으로 가압코일스프링(12)내로 돌입하고 있는 것을 특징으로 하는 주사기.4. The sleeve according to claim 3, wherein the sleeve as the spring bearing 11 for the larger pressure coil spring 12 has an annular collar 13 protruding radially outward, and at least partially the pressure coil spring 12.
