1. A compression tube attaching-detaching unit comprising:
an arm configured to support a compression tube;
a connecting pin; and
an attaching-detaching mechanism portion configured to mount the arm on a radiographic fluoroscopic imaging apparatus by being detachably coupled with the connecting pin,
wherein the connecting pin has a shaft portion and a flange portion positioned at a tip end of the shaft portion,
wherein the attaching-detaching mechanism portion includes:
a main body having a groove portion into which the flange portion is relatively slidably inserted;
a lid portion having a cut-out portion into which the shaft portion is relatively slidably inserted, the lid portion being fixed to the main body to accommodate the flange portion between the lid portion and the main body;
a locking portion attached to the main body to be positioned on a slide insertion path of the flange portion, the locking portion being provided so as to be contactable and separatable with respect to the lid portion and being configured to receive a biasing force in a direction approaching the lid portion; and
an unlocking portion attached to the main body, the unlocking portion being configured to separate the locking portion from the lid portion against the biasing force,
wherein an inclined surface that comes into slide contact with the flange portion is provided at a lid portion side of the locking portion, and
wherein the inclined surface is inclined to be positioned in a slide insertion direction of the flange portion as the inclined surface advances toward a tip end of the locking portion.
