Abstract
A pressure switching mechanism includes a rotatable support, a biasing member, and a switching rotation member. The rotatable support rotates around a first rotation shaft to support a contact member such that the contact member is movable in a direction toward or away from a contacted member. The biasing member has one end connected to a biased portion of the rotatable support, which is located on a side opposite the first rotation shaft with respect to a virtual line passing through a contact portion between the contact member and the contacted member, and applies a biasing force to the rotatable support. The switching rotation member is connected to another end of the biasing member opposite the one end of the biasing member, rotates around a second rotation shaft, and has a rotation operating end which is on a side opposite the second rotation shaft with respect to the virtual line.
