An electric field stirring apparatus, in which a droplet as a liquid disposed between a first electrode and a second electrode disposed to face each other is vibrated and stirred by an electric field generated between the first electrode and the second electrode, the second electrode having a groove formed along a first direction on an electrode surface facing the first electrode, includes a movement mechanism that reciprocally moves the first electrode relative to the second electrode in a second direction intersecting the first direction in a state in which the first electrode and the second electrode face each other during a period in which the electric field is generated.

An escape lever suppresses energy loss and provides strong resistance to external shocks. An escape lever has a pallet fork; a pallet formed in unison with the pallet fork for engaging the escape wheel; and a pallet staff that is a pivot of the pallet fork and passes through the pallet fork. The pallet has a locking surface that the locking corner of the escape wheel contacts in the unlocking period when the escape wheel is released by the pallet and freed to move. The locking surface is shaped so that the draw angle formed by a normal to the contact point with the locking corner of the escape wheel, and a line through the contact point and the axis of the pallet staff, remains constant during the unlocking period.
