1. A barrel support apparatus for horizontally supporting a barrel of an injection apparatus which can move forward and backward, comprising:
a barrel support member configured to support the barrel from below and being placed on a support base supported by a spring;
a leg portion which supports the barrel support member and is configured to move following the forward and backward movement of the barrel; and
a detachment means configured to detach the support base from the barrel support member, against the elastic force of the spring that supports the support base, wherein
the detachment means is configured to move the support base downward from a first position to a second position below the first position in a vertical direction when the barrel starts to turn,
the first position is a position at which the support base supports the barrel and at which an upper surface of the support base comes into contact with a lower surface of the barrel support member, and
the second position is a position at which a gap is formed between the lower surface of the barrel support member and the upper surface of the support base as a result of compression of the spring.
