Document Type and Number:
Japanese Patent JP6525160
Kind Code:
B2
Abstract:
Provided is a cap for a handwheel that opens and closes a valve, capable of being readily attached to the handwheel without requiring a large space around the handwheel. The cap has easily switchable two working modes: One is a co-rotation mode where the cap is capable of rotating with the handwheel and the other is an independent rotation mode where the cap is capable of rotating independently of the handwheel. The cap has an internal casing to be securely fitted to the handwheel; an external casing being rotatable around its axis and having the internal casing in an interior thereof; a clutch for connecting the external casing with the internal casing and for disconnecting the former from the latter; and a maintaining member for keeping the external casing rotatable independently of the internal casing when they are disconnected by the clutch.
