Abstract: An automatic braking control device includes a temperature obtaining section for obtaining an index value of a temperature of brake fluid, a collision prediction time calculation section for calculating collision prediction time of a vehicle with an object, a collision determination section for determining whether the collision prediction time is less than or equal to a threshold, and a pressure control section for controlling a start timing of pressurization of the brake fluid when the collision prediction time is less than or equal to the threshold. The pressure control section sets the start timing to a first timing when the index value is a first temperature and to a second timing when the index value is a second temperature higher than the first temperature. Time from determination of the collision determination section to the first timing is shorter than time from the determination to the second timing.

Abstract: A hydraulic actuator for a belt type continuously variable transmission, with which a smooth operation is secured and both superior productivity and reduced manufacturing costs can be expected, includes a first cylinder provided on a movable sheave, a drum having a first drum portion that covers the first cylinder and a second drum portion that is fitted to a boss portion of the movable sheave and formed with a plurality of projections, a first plunger having a cylindrical portion that is fitted to the first cylinder and the second drum portion to form a first hydraulic chamber, and a second plunger fitted to the cylindrical portion and the first cylinder to form a second hydraulic chamber. An oil passage connecting the first hydraulic chamber and the second hydraulic chamber is formed by a gap between the second drum portion and cylindrical portion, which are fitted together.
