  • Patent number: 11673540
    Abstract: A vehicle braking device includes: a brake fluid pressure generation device arranged in a storage chamber separated from a vehicle cabin; and a brake operation part mechanically connected to the brake fluid pressure generation device, the brake operation part being not provided in the vehicle cabin. The brake fluid pressure generation device includes a cylinder and pistons configured to slide inside the cylinder. The brake fluid pressure generation device is configured to generate brake fluid pressure in accordance with strokes of the pistons. The brake fluid pressure generation device is arranged such that a sliding direction of the pistons is along a direction different from the vehicle front-rear direction in a plan view.

  • Patent number: 11400910
    Abstract: A vehicle includes a vehicle cabin, a storage chamber, and a partition wall separating the storage chamber from the vehicle cabin. The storage chamber is arranged on at least one side of the vehicle cabin in the vehicle front-rear direction. The partition wall has an opening and the storage chamber communicates with the vehicle cabin via the opening. A cover configured to open and close the opening is provided over the opening. A brake fluid pressure generation device is stored in the storage chamber. The brake fluid pressure generation device includes a reservoir tank in which hydraulic fluid is accumulated and is arranged at a position facing the opening.

  • Patent number: 11299193
    Abstract: An electric vehicle includes: a motor; a braking device for wheel braking, the braking device including a brake fluid pressure generation device; an air-conditioning device; and a battery as a power source for the motor. The vehicle is not provided with a driver seat that allows a user to operate a steering wheel, an accelerator pedal, and a brake pedal in a state where the user sits on the driver seat, and the vehicle is configured to perform automated driving. A first storage chamber and a second storage chamber are provided in a first end portion and a second end portion of the vehicle in the vehicle front-rear direction, respectively, such that the first storage chamber and the second storage chamber partially overlap a vehicle cabin in the vehicle front-rear direction. A third storage chamber is provided under a floor of the vehicle cabin.

  • Patent number: 11104320
    Abstract: Provided is a brake bleeding device for bleeding air accumulated in brake fluid inside a braking device provided in a vehicle. The brake bleeding device includes: a master cylinder constituting a part of the braking device and provided inside a front-side storage chamber, the master cylinder being configured to generate brake hydraulic pressure in accordance with a stroke of an input piston; a brake pedal unit provided inside the front-side storage chamber and configured to give pressing force in a stroke direction to the input piston when a link mechanism connected to the input piston via a rod is operated; and an operating lever attached to the link mechanism in a state where the link mechanism is operable by the operating lever. The operating lever extends downward to a position where the operating lever is accessible from outside the front-side storage chamber.
