Electric brake apparatus and electric disk brake

An electric brake apparatus comprising:

• a braking mechanism configured to press a braking member to a braked member;
• an electric motor configured to drive the braking mechanism;
• a control unit connected to the electric motor;
• a first connector portion connected to the control unit and configured for at least any one of power feeding or input of a predetermined signal;
• a second connector portion connected to the control unit and configured to include at least a part of a use of the first connector portion;
• and
• a third connector portion connected to the control unit and configured for input of a signal related to a wheel speed,
• wherein:
• the control unit is a control substrate section having at least one control substrate;
• the braking member is disposed across the electric motor from the control substrate section in a rotation axis line direction of the electric motor;
• and
• the first connector portion, the second connector portion, and the third connector portion extend to a braking member side in the rotation axis line direction of the electric motor.

An electric disk brake comprising:

• a mounting member configured to be fixed to a non-rotating portion of a vehicle and disposed over an outer peripheral side of a disk rotor;
• a caliper main body disposed to the mounting member to be movable in an axial direction of the disk rotor and including a braking mechanism configured to press a friction pad to the disk rotor;
• an electric motor configured to drive the braking mechanism;
• a control substrate including a first control substrate section connected to the electric motor and having one of redundant control systems and a second control substrate section connected to the electric motor and having another of the redundant control systems;
• a first connector connected to the first control substrate section and configured for power feeding and input of one of redundant signals;
• a second connector connected to the second control substrate section and configured for power feeding and input of another of the redundant signals;
• and
• a third connector connectable to both the first control substrate section and the second control substrate section and configured for input of a signal from a wheel speed detection sensor,
• wherein:
• the braking member is disposed across the electric motor from the control substrate section in a rotation axis line direction of the electric motor;
• and
• the first connector portion, the second connector portion, and the third connector portion extend to a braking member side in the rotation axis line direction of the electric motor.
