Claim:
A side lock device for attaching a first member to a second member to be openable, the side lock device comprising: a pair of lock arms; a housing which holds the lock arms movably, said housing comprising: a main body comprising an upper surface and a front surface; a base body, extending from said main body, said base body comprising a pair of sidewalls and a front wall, said pair of side walls extending perpendicularly from the front surface of the main body and said front wall being disposed parallel to the front surface of the main body; a housing cavity disposed between said main body and said base body, within a space between the sidewalls of said base body; and holding grooves disposed within said main body for receiving the lock arms; a slider comprising holes which engage with the lock arms and urge the lock arms to protrude and retract linearly, the slider disposed in the housing cavity; an elastic member which elastically urges the slider toward a predetermined direction; and a stopper protrusion formed on a side of the slider, and projecting outwardly from the side of said slider, to prevent said slider from vertically detaching from said housing, wherein, when the slider is operated against the elastic member, the lock arms are retracted, wherein the holes engage with protrusions of the lock arms and comprise a reverse-V shape, wherein openings are formed on both side surfaces of the slider to continue to outer ends of the holes, the openings including cutouts in a wall of the slider on which the holes arc formed, the cutouts extending from the holes to side walls extending from the wall of the slider, the openings respectively communicating with the holes so as to allow the protrusions of the lock arms to be inserted into the holes from the side surfaces of the slider through the openings, and the openings aligning with the holding grooves when the slider is assembled into the housing, wherein the openings are open during a process of assembling the slider into the housing, and wherein end faces of the openings, through which the lock arms pass, are closed by the housing when the slider has been assembled into the housing.
