PROBLEM TO BE SOLVED: To provide a syringe capable of surely tilting a cannula relating to the syringe.SOLUTION: By engaging an engaging means 8 provided in a plunger 4 with a means 7a to be engaged provided in an inner hub 7 and moving back the plunger, the cannula 2 can be housed inside a barrel together with the inner hub 7. The engaging means 8 is provided with a cylindrical member 8A provided on the distal end part of the plunger, an engaging part 8d which is provided on the cylindrical member and engaged with the means to be engaged of the inner hub, and pressurizing parts 8e and 8f which are abutted on the means engaged with the engaging part and pressurize the engaged means to be eccentric outwards in the radial direction from the center axis L of the cylindrical member and make the distal end part of the cannula eccentric outwards in the radial direction from the center axis of the barrel further. By this invention, since the engaged means abutted on the pressurizing parts can be surely pressurized to be eccentric outwards in the radial direction from the center axis of the cylindrical member by the pressurizing parts 8e and 8f, the cannula is surely tilted.COPYRIGHT: (C)2009,JPO&INPIT【解決手段】 プランジャ4に設けた係合手段8を内ハブ7に設けた被係合手段7aに係合させてプランジャを後退させることで、カヌラ2を内ハブ7ごとバレル内に収納することができるようになっている。上記係合手段8は、上記プランジャの先端部に設けた筒状部材8Aと、この筒状部材に設けられて上記内ハブの被係合手段に係合する係合部8dと、さらに上記係合部に係合した被係合手段に当接して該被係合手段を筒状部材の中心軸Lから半径方向外方に押圧偏心させて、上記カヌラの先端部をバレルの中心軸から半径方向外方に偏心させる押圧部8e、8fとを備えている。【効果】 押圧部8e、8fによって、該押圧部に当接する被係合手段を筒状部材の中心軸から半径方向外方に確実に押圧偏心させることができるので、カヌラを確実に傾かせることができる。【選択図】 図5
