Abstract: In a webbing take-up device, a structure for interlocking a second lock pawl with a first lock pawl is only a shaft. It also suffices for switching between restricting of rotation of a lock ring and cancelling of the restricting to be carried out merely by moving a piston by gas pressure generated at a gas generator. In this way, by a simple structure, it is possible to switch between a mode, in which torsional deformation is brought about at a sub torsion main body of a sub torsion shaft, and a mode, in which torsional deformation is not brought about at the sub torsion main body of the sub torsion shaft.

Abstract: In a webbing take-up device, due to actuation of a pre-tensioning mechanism when a vehicle collision, a piston is moved, rack teeth of the piston mesh with pinion teeth of a pinion, causing the pinion rotate and a spool to be rotated in the take-up direction. In a state where a large rotational force in the pull-out direction is acting from an occupant on the pinion, through a webbing and the spool, a rack tooth is broken by a pinion tooth when the rack teeth initially mesh with the pinion teeth, especially by a tip end of the rack tooth meshing with the pinion tooth. Therefore, sticking-in of the pinion teeth rack teeth and the pinion teeth can be suppressed, or easily eliminated, enabling loss in force transmitted from the piston to the pinion to be reduced.

Abstract: An electronic control unit executes throttle torque reduction control for decreasing an engine torque by reducing a throttle opening degree during an upshift of an automatic transmission with respect to the throttle opening degree before a start of the upshift. During the upshift of the automatic transmission, the electronic control unit actuates a waste gate valve in a closing direction with respect to a position of the waste gate valve before the start of the upshift in parallel with execution of the throttle torque reduction control. Thus, a decrease in supercharging pressure due to execution of the throttle torque reduction control is suppressed during the upshift, and the engine torque that has been temporarily decreased in an inertia phase of the upshift recovers immediately after the upshift, so it is possible to suppress deterioration of drivability.
