A relation of L1 to L2 satisfies L1>L2, where L1 denotes a distance between the second support shaft and a biasing position and L2 denotes a distance between the second support shaft and a first pressing position. A relation of L3 to L4 satisfies L3>L4, where L3 denotes a distance between the first support shaft and the pressing position and L4 denotes a distance between the first support shaft and a second pressing position.
