A brake device for braking a stroller, which has an axle and a wheel mounted rotatably thereon, includes a support post secured relative to and extending uprightly from the rear axle, and a mounting frame disposed on the support post and extending beyond the uppermost part of the wheel. The mounting frame includes two lug portions extending in a first direction transverse to the support post and towards the wheel. The lug portions are spaced apart from each other in a second direction transverse to the first direction. A brake shoe includes a pair of arresting portions with two anchoring ends which are mounted pivotally on the lug portions, respectively. The arresting portions extend in the first direction, are spaced apart from each other in the second direction, and form two arresting surfaces therebeneath. A biasing spring has a biasing action along a lengthwise axis, and two ends fixedly secured relative to the support post and to the brake shoe, respectively. The spring is disposed between the arresting portions such that such that when the arresting portions are in a retracted position, the lengthwise axis is at an angle of at least 90 degrees, the angles being measured in a counterclockwise direction from the first direction.

[ I claim:] [1.] A brake device for a stroller which includes a wheel member with a tire, and a rear axle having the wheel rotatably mounted thereon, the brake device comprising:a support post adapted to be disposed inboard to the wheel member, and adapted to be fixedly secured relative to and extending uprightly from the rear axle beyond an uppermost part of the tire;a mounting frame disposed on said support post and adapted to be located beyond the uppermost part of the tire, said mounting frame including two lug portions respectively extending in a first direction transverse to said support post and towards the tire and spaced apart from each other in a second direction transverse to said first direction;a brake shoe including a pair of arresting portions with two anchoring ends which are mounted pivotally on said lug portions respectively, said arresting portions extending in said first direction and being spaced apart from each other in said second direction so as and forming two arresting surfaces therebeneath, said arresting surfaces being adapted to arrest two spaced locations on the uppermost part of the tire, said arresting portions being pivotable around a pivot axis which is parallel to said second direction between a retracted position, where said arresting portions are lifted away from the spaced locations on the tire, and an arresting position, where said arresting portions depress said uppermost part of the tire at the spaced locations; anda biasing spring having a biasing action along a lengthwise axis, and two ends fixedly secured relative to said support post and to said brake shoe, respectively, said biasing spring being disposed between said arresting portions such that when said arresting portions are in said retracted position, said lengthwise axis is at an angle of at least 90 degrees measured in a counterclockwise direction from said first direction and such that when said arresting portions are in said arresting position, said lengthwise axis is at an angle of less than 90 degrees measured in the counterclockwise direction from said first direction.
