A tape threading mechanism for a magnetic tape unit uses a cartridge-contained magnetic tape with a leader-block attached at an end of the magnetic tape. The tape threading mechanism pulls out the leader-block from the cartridge, performs a tape threading/unthreading and inserts the leader-block back into the cartridge by way of a threading arm. The threading arm is connected to a rotational axis thereof at a first end. A second end of the threading arm is provided with a pin for carrying the leader-block and includes a linkage of at least two arms. At least one of the two arms has an elastic member which allows the threading arm to expand and contract lengthwise.
