PROBLEM TO BE SOLVED: To ensure injector force transmission, simplify the shape of a frame body, and maintain operability of an injector even if shock is applied to a connector. SOLUTION: An injector is so provided with an outside part 40 and an inside part 50 which are fitted slidingly each other as to be expandable in a specified direction. The outside part is provided with a spring part 43 expanding in said specified direction. A spring part 43 is made capable of displacement between a first behavior fitted to the inside part in said specified direction to inhibit contraction of an injector and a second behavior not fitted thereto. On the other hand, the inside part is provided with a protrusion 52b capable of displacement, protruded in a first direction orthogonal to said specified direction. The protrusion 52b is placed and held in said second behavior by slackening the spring part 43, displacement is generated by means of a holder part 14 according to forwarding movement of the injector, and the placement and holding of the spring part 43 is released. Moreover, the connector is provided with a support receiving part 52e protruded in the second direction orthogonal to any of said specified direction and said first direction from the protrusion 52b and widening a face for placing and holding the spring part 43.
