Abstract
A structure is provided for preventing detachment of a lighter nozzle cap in a lighter having a main lighter body, a burner located on top of the main lighter body for burning fuel to produce a flame, an operation member located on top of the main lighter body for lighting the burner and a nozzle cap for covering a zone surrounding the burner from above. The structure includes a pair of posts projecting from the top of the main lighter body, each post being formed with a socket, a pair of detachment preventing catches provided one on either side wall of the nozzle cap to be engageable with the sockets, and retaining portions provided at portions of the side walls near the catches for engaging with an upper inner edge of the main lighter body to prevent spreading deformation of the side walls.
