[0002]
[Prior art]
Conventionally, in the slide rail, a guide member that acts as a guide when the extracted moving member is mounted again is formed from a synthetic resin material, and this is formed by a member that holds the moving member slidably. It was provided at the front end. (For example, see Patent Document 1)
On the other hand, in order to prevent the moving-side member from being accidentally popped out, a lock mechanism that holds the stored moving-side member is provided at the rear end of the member that slidably holds the moving-side member. (For example, see Patent Document 2)
That is, in order to simultaneously obtain a guiding function for facilitating mounting of the moving member and a holding function for holding the moving member in the retracted state, members corresponding to respective purposes must be separately attached to the slide rail. For this reason, the number of members is increased, and it takes time and effort to install, and the member management becomes complicated, resulting in an increase in cost.
