A problem to be solved by the present invention is to provide a syringe augmentation instrument with which it is possible to self-administer a hypodermic injection in a manner which is safe and easy to operate. Provided is a syringe augmentation instrument, which is attached to a syringe which comprises: a syringe main body, further comprising a cylindrical barrel which is filled with an injection, and a hypodermic needle which is disposed on one end of the barrel in the axial direction thereof; and a cap which is mounted on the syringe main body so as to cover the hypodermic needle. Said syringe augmentation instrument comprises: a casing body wherein it is possible to insert and remove the syringe main body in an insertion and removal direction which is at right angles to the axial direction of the barrel; a detachment member which detaches the cap from the syringe main body which is inserted into the casing body; an extraction restriction part which restricts the extraction of the syringe main body from the casing body; and an operation part which is capable of switching between a pulled-up state of being pulled up from, and a pushed-down state of being pushed down to, the casing body. The detachment member and the extraction restriction part are operated in accordance with a pulling-up operation and a pushing-down operation of the operation part with respect to the casing body.
