Abstract
A questionnaire survey about overalls was put into effect in woman engineer of 148 people who have worked for more than 6 months at a building site in fiscal year 2015. I looked back to that case's questionnaire result by this thesis as well as a hearing investigation was performed about the latest shape of the ladies' overalls, steel-toed shoes, helmet and safe glasses, so it was reported. As a result, the ladies' size was set up about overalls as well as the silhouette and the structure which tends to move were studied. The helmet was also light-weight and something with the shape which matches a female hairstyle had been developed. The steel-toed shoes were light-weight and there was also something with the shape like the athletic shoes. Safe glasses, gloves for work and something with the size which is also for ladies for a safe area had been developed. Heavy overalls the size which matches a questionnaire result doesn't match found out that improvement is developed.
