摘要：
A ballpoint (10) pen has an ink reservoir tube (12) which stores ink (13), a point assembly (14) disposed in the front of the ink reservoir tube (12), and a ball bearing (16) held at the front end of the point assembly (14). The ball bearing (16) is a shape memory alloy (SMA), Preferably a TiNi intermetallic compound or a TiNi based alloy. The ball bearing (16) solves the problem of ink failing to flow when the ballpoint pen (10) is dropped on the ground.
