摘要: A cap sheet metal (and pivot metal) is configured to be able move linearly with a arm an stay) via engagement between hole and fitting shaft. Furthermore, the can pivotally respect using shaft, which engages hole, as pivotal Thus, even if, for example, direction of biasing toward applying roller deviates or positional relationship slightly, liquid holding member moves pivots in bias depending on deviation. As result, contacting pressure portion made uniform.
