摘要： The present invention relates to a hat for preventing a visual field from being covered. According to the present invention, the hat does not come off and does not cover the visual field when the user wearing the hat, which is attached to clothing, turns his or her head right or left or bends his or her body forward, thereby eliminating the risk of accidents. In addition, since the hat adheres to the wearer's head, the thermal effect and the wearing sensation are improved.

摘要： Dual capacity compressor including a power generating part (20) having a reversible motor (21, 22) and a crank shaft (23) inserted in the motor (21, 23), a compression part (30) having a cylinder (32), a piston (31), and a connecting rod (33), a crank pin (110) in an upper part of the crank shaft (23) eccentric to an axis of the crank shaft, an eccentric sleeve (120) rotatably fitted to the crank pin (110), and the connecting rod (33) respectively, a key member (130) for positive fastening of the eccentric sleeve (120 ) to the crank pin (110) in all rotation directions of the motor, and an eccentric mass (200) provided to the eccentric sleeve (120) for rotating the eccentric sleeve (120) around the crank pin (110), thereby preventing relative motion between components that sustain the eccentricity, and permitting a smooth motion between the components.
