The flow paths FP1 to FP4 include a first flow path FP1, a second flow path FP2, a third flow path FP3, and a fourth flow path FP4. The flow paths FP1 to FP4 are filled with hydraulic oil (fluid).

By operating the lever F1, the piston F3 moves in the cylinder F2, and hydraulic pressure acts on the braking device 12 via the first flow path FP1. The operating device F further includes a reservoir F5 that stores hydraulic oil so that the hydraulic oil can be supplied into the cylinder F2. A diaphragm (not shown) is provided in the reservoir F5. In the present embodiment, when the lever F1 is operated, the piston F3 moves in the cylinder F2, and hydraulic pressure acts on the braking device 12 via the first flow path FP1.

The hydraulic mechanism 22 includes a first electromagnetic valve 22A and a second electromagnetic valve 22B. The first electromagnetic valve 22A and the second electromagnetic valve 22B are driven by electric power supplied from, for example, the battery BT. For example, the first electromagnetic valve 22A is fluidly connected to the operating device F via the first flow path FP1, and is fluidly connected to the caliper 16 via the second flow path FP2. The first electromagnetic valve 22A is provided to open and close between the first flow path FP1 and the second flow path FP2. For example, the first electromagnetic valve 22A is opened so that the hydraulic oil flows in a non-energized state, and is closed so that the hydraulic oil does not flow in an energized state.

  For example, the second electromagnetic valve 22B is provided so as to open and close between a third flow path FP3 branched from the first flow path FP1 and a fourth flow path FP4 branched from the second flow path FP2. For example, the second solenoid valve 22B is closed so that hydraulic fluid does not flow in a non-energized state, and is opened so that hydraulic fluid flows in a conductive state. The opening / closing operations of the first electromagnetic valve 22A and the second electromagnetic valve 22B are controlled by, for example, a control device 26 described later.

  The brake system 10 further includes an adjusting device 24 provided between the braking device 12 and the operating device F in the flow paths FP1 to FP4. For example, the adjusting device 24 is fluidly connected to the third flow path FP3. In the present embodiment, the adjusting device 24 is an accumulator. The adjusting device 24 includes a storage chamber 24A configured to store the fluid in the flow paths FP1 to FP4, and an electric change mechanism 24B that changes the volume of the storage chamber 24A. The electric change mechanism 24B is provided in the storage chamber 24A, for example. In the present embodiment, the electric change mechanism 24B is a diaphragm. The electric change mechanism 24B shown by a solid line in FIG. 3 shows a state in which the volume of the storage chamber 24A is deformed to be maximum. The two-dot chain line electric change mechanism 24B shown in FIG. 3 shows a deformed state so that the volume of the storage chamber 24A is minimized.

  The caliper 16 holds the rotating body DR with the friction member 14, for example. The friction member 14 includes a first friction member 14A and a second friction member 14B arranged so as to sandwich the rotating body DR therebetween. The caliper 16 biases each piston 16B so that the housing 16A, a pair of pistons 16B displaced by the pressure of the hydraulic oil supplied from the flow paths FP1 to FP4, and the pair of pistons 16B are displaced in directions away from each other. And an urging member 16C. The inside of the housing 16A is filled with hydraulic oil. In the present embodiment, the first friction member 14A is attached to one piston 16B, and the second friction member 14B is attached to the other piston 16B. The biasing member 16C biases the pair of pistons 16B via the first friction member 14A and the second friction member 14B. The biasing member 16C is, for example, a spring. One of the pair of pistons 16B and one of the first friction member 14A and the second friction member 14B may be omitted. That is, the rotating body DR may be braked by only one of the first friction member 14A and the second friction member 14B. Alternatively, one of the first friction member 14A and the second friction member 14B may be fixed and only the other may be moved.

  When the first electromagnetic valve 22A is opened and the second electromagnetic valve 22B is closed, the lever F1 of the operating device F is operated, so that the hydraulic oil in the cylinder F2 is supplied to the first flow path FP1, the first electromagnetic valve. It is supplied to the caliper 16 through 22A and the second flow path FP2. Then, the pair of pistons 16B are displaced so that the first friction member 14A and the second friction member 14B approach the rotating body DR. In this way, the hydraulic pressure acts on the braking device 12 in accordance with the input to the operating device F, and the rotating body DR is braked by the braking device 12. On the other hand, when the input to the operating device F is released, the piston 16B is displaced so that the first friction member 14A and the second friction member 14B are separated from the rotating body DR by the biasing force of the biasing member 16C. Then, the hydraulic oil in the housing 16A is returned to the cylinder F2 and the reservoir F5 through the flow paths FP1, FP2, etc., and the lever F1 of the operating device F is returned to the initial position by the urging force of the urging member F4. .

  When the lever F1 of the operating device F is operated, when the first electromagnetic valve 22A is closed and the second electromagnetic valve 22B is opened, the hydraulic oil in the housing 16A is in the second flow path FP2 and the fourth flow path. It is supplied to the adjusting device 24 through the FP4, the second electromagnetic valve 22B, and the third flow path FP3. In this case, the hydraulic pressure acting on the braking device 12 is reduced so that the braking force acting on the rotating body DR decreases. After that, when the first electromagnetic valve 22A is opened and the second electromagnetic valve 22B is closed, the braking force acting on the rotating body DR is increased according to the input to the operating device F so as to act on the braking device 12. The hydraulic pressure is increased. In this way, the braking force acting on the rotating body DR is adjusted by controlling the first electromagnetic valve 22A and the second electromagnetic valve 22B. On the other hand, when the input to the operating device F is released, the inside of the cylinder F2 is in the atmospheric pressure state, so that the hydraulic oil in the adjusting device 24 is returned to the flow paths FP1 to FP4, and the lever F1 of the operating device F is initially The hydraulic oil in the housing 16A is returned to the cylinder F2 and the reservoir F5 so as to return to the position.

  As indicated by a broken line in FIG. 3, the braking device 12 may further include an electric drive unit ED that drives the caliper 16 and a hydraulic pump HP that adjusts the hydraulic pressure acting on the caliper 16. The electric drive unit ED is electrically connected to the operation device F by, for example, an electric wire EW. The electric drive unit ED is an electric motor. The hydraulic pump HP is fluidly connected to the caliper 16 via the flow paths FP1 to FP4, for example. The inside of the hydraulic pump HP is filled with hydraulic oil. When the lever F1 of the operating device F is operated, the electric drive unit ED is driven according to the detection result of a sensor (not shown) for detecting the rotation amount of the lever F1, and the caliper is operated by operating the hydraulic pump HP. The hydraulic pressure acts on 16. Further, when the electric drive unit ED is controlled by the control device 26 described later, the hydraulic pump HP is controlled such that the braking force acting on the rotating body DR is increased or decreased. In this example, the hydraulic mechanism 22 may be omitted from the braking device 12. The braking device 12 may be configured to brake the rotating body DR when the caliper 16 is mechanically or electrically driven by the electric drive unit ED. In this case, the braking device 12 and the operating device F may be mechanically connected or electrically connected.

  As shown in FIG. 4, the brake system 10 further includes a control device 26 configured to brake the rotating body DR by the braking device 12. The control device 26 includes a control unit 28 that executes adjustment control for adjusting the braking force acting on the rotating body DR based on braking-related information different from the rotation speed of the rotating body DR. The control unit 28 is a CPU (Central Processing Unit) or an MPU (Micro Processing Unit). The controller 28 adjusts the braking force by controlling the first electromagnetic valve 22A and the second electromagnetic valve 22B, for example, in adjustment control. The adjustment control is control related to ABS (Antilock Brake System). The rotational speed of the rotating body DR is the same as the rotational speed of the tire T, the rotational speed of the rim R, the rotational speed of the spoke S, and the rotational speed of the hub shell HS. That is, the rotational speed of the rotating body DR indicates the rotational speed of the wheel W.
