PURPOSE:To make compact the whole handle device by utilizing a cam inclined plane which is integrally formed with a handle or can be turned at least integrally with the handle. CONSTITUTION:A guide pin 4 is erected near the nose of a rod section 3 of an end section extending to the inside of the handle 2 of an operation level 2. The erected guide pin 4 functions as a cam follower cooperating with a cam inclined plane forming an integral section with the handle 2. The cam inclined plane is fundamentally made up in a shape that obliquely cuts one end of a cylindrical body 5. A compression spring 9 is arranged between an annular stage section 7 of the operation level 2 and an end surface 8 of the cylindrical body 5, a torsion spring for returning the handle to an original angular location is not needed, and only the compression spring is provided, thus the whole handle device is made compact. |
