Abstract: A seat surface of a flat head bolt and a seat surface of a front plate are in contact with each other such that a tightening axial tension acts at an axial tension action point in an axial cross-section. A normal vector is perpendicular to the seat surface of the front plate and passes through the axial tension action point in the axial cross-section. An axial tension reach point is an intersection point between the normal vector and a shoe front surface in the axial cross-section. The normal vector intersects the shoe front surface at the axial tension reach point in the axial cross-section, and the axial tension reach point is included in a range of a shoe part.

Abstract: A vehicle control device includes: an actuator drive controller configured to control a drive of an actuator; a main motor drive controller configured to control a drive of a main motor; and a stuck determiner. The stuck determiner determines a stuck of the actuator based on a detection value of a sensor unit that detects a physical quantity changed according to a drive state of the actuator. The main motor drive controller is configured to perform an engaging surface pressure reduction control for reducing an engaging surface pressure between a parking gear and a parking lever by driving the main motor, when the stuck determiner determines that the actuator is stuck in releasing a parking lock of the vehicle.
