Problems solved by technology

[0011] However, in the vehicle braking device of JP2007-218361A, the connection of the electric actuator to the vehicle body becomes complicated, and the electric actuator must be placed so that the electric actuator cannot interfere with the suspension components (such as the trailing arm or the vehicle body). The location of the tire of the wheel to which the brake is attached)
This reduces the degrees of freedom in arranging the electric actuator

[0075] Refer below Figures 1 to 3 The first embodiment will be described. A steering knuckle 113 having a frame portion 113a is fixed to the rear end of a trailing arm 112 extending in the front-rear direction of the four-wheeled vehicle, and the trailing arm 112 constitutes a part of a suspension 111 by which the right rear wheel is supported in a suspended manner. on the body of a four-wheeled vehicle. The shaft 114 of the right rear wheel placed on the laterally outer side of the frame portion 113a is rotatably supported on the frame portion 113a.

[0076] A brake shoe 116 of a drum brake 115 mounted on the right rear wheel is fixed to the frame portion 113a. The anchor block 121 is fixedly arranged on the lower part of the brake base plate 116, and the anchor block 121 constitutes a fulcrum on which a group of front main brake pads 117 and rear secondary brake pads 118 expand or contract. Friction pads 119, 120 configured to rotate with the right rear wheel are attache...

[0110] Refer below Figures 6 to 10 A third embodiment will be described. First, in Figures 6 to 8 In this, a steering knuckle 213 having a frame portion 213a is fixed to the rear end of a trailing arm 212 extending in the front-rear direction of the four-wheeled vehicle, the trailing arm constituting a part of the suspension 211, one of the left and right rear wheels of the four-wheeled vehicle The left rear wheel is supported by it in a suspended manner on the body of the vehicle. The shaft 214 of the left rear wheel placed on the laterally outer side of the frame portion 213a is rotatably supported on the frame portion 213a.

[0111] The wheel brake provided on the left rear wheel is a drum brake 215, and the brake shoe 216 of this drum brake 215 is fixed to the frame portion 213a. The anchor block 221 is fixedly arranged on the lower part of the brake base plate 216, and the anchor block 221 constitutes a fulcrum on which a group of front main brake pads 217 and rear s...
