摘要： A joint block includes a block body, a closing member mounted in a recessed part formed on the other end side of the block body, a seal mechanism that includes a circular projection formed on an opposing surface of the block body, and seals an area between the block body and the closing member by the circular projection biting into the other opposing surface around an opening of a first flow path, a swaging part that is formed on the block body and presses the closing member toward the opposing surface, and an engaging part formed by an inner peripheral part of the recessed part and an outer peripheral part of the closing member that engages with the inner peripheral part. A pressing force that presses the circular projection of the seal mechanism against the other opposing surface is shared by the swaging part and the engaging part.

摘要： To provide a manual valve device suitable for a miniaturized and integrated fluid control system, the manual valve device includes a casing having a tubular shape and incorporating a drive mechanism, an operation member for activating the drive mechanism, and a cam part that converts a force acting on the operation member into a driving force of the drive mechanism. The manual valve device further includes a protective cover provided on an upper end side of the casing and covering at least a portion of the operation member. The operation member includes an attaching part that allows removable attaching of an auxiliary tool for causing a force required for activation of the drive mechanism to act on the operation member. The protective cover is formed so as to allow access to the attaching part of the operation member by the auxiliary tool.
