TOILET SEAT DEVICE

To provide a toilet seat device with a cut-off device provided so as to be heated by a heating element and capable of electrically cutting off energization of the heating element, in which the heat generated by the heating element is transmitted to the cut-off device efficiently.SOLUTION: A toilet seat device 1 includes a toilet seat part 20 having a seating surface Sb1 and internally formed of a space, and a heating device 50 arranged so as to cover a covered face Sb3 of the inside surface of the toilet seat part 20 and heating the seating surface Sb1. The heating device 50 includes: a sheet part 51 provided in a sheet form and arranged so that one side Ss1 may cover the covered face Sb3; a heating element 52 arranged to the sheet part 51 and generating heat by being energized; a dense part 53 provided so as to increase a heating value in comparison with the other part by that the heating elements 52 are densely arranged more than the other part; and a cut-off device 54 arranged between the covered face Sb3 and the dense part 53, and provided so as to electrically cut off the energization of the heating elements 52 by being heated by the dense part 53.SELECTED DRAWING: Figure 4 【課題】発熱体によって加熱されて、発熱体の通電を電気的に遮断可能に設けられた遮断装置を備える便座装置において、発熱体が発する熱を遮断装置に効率よく伝達させること。【解決手段】便座装置１は、着座面Ｓｂ１を有し、内部に空間を形成された便座部２０と、便座部２０の内側面のうち被覆面Ｓｂ３を覆うように配置され、着座面Ｓｂ１を加熱する加熱装置５０と、を備えている。加熱装置５０は、シート状に設けられ、一方面Ｓｓ１が被覆面Ｓｂ３を覆うように配置されたシート部５１と、シート部５１に配置され、通電されることにより発熱する発熱体５２と、他の部位よりも発熱体５２が密集して配置されることにより、他の部位に比べて発熱量が大きくなるように設けられた密集部５３と、被覆面Ｓｂ３と密集部５３との間に配置され、密集部５３によって加熱されることにより発熱体５２の通電を電気的に遮断可能に設けられている遮断装置５４と、を備えている。【選択図】 図４
