A latch unit of the invention includes a casing having a holding chamber for holding a striker and a side chamber situated adjacent to the holding chamber, and a responding member housed in the side chamber. The holding chamber and the side chamber are partitioned by an elastic member projecting toward an introduction opening of the holding chamber for introducing the striker to be attached to the latch unit. The electric member is provided with an engaging projection for engaging the striker as the striker is inserted into the holding chamber. The side chamber is provided with an urging device for urging the responding member toward a base portion of the elastic member. An urging force of the urging device is set such that when an inertia force is applied to release an engagement of the elastic member and the striker to thereby extract the striker from the holding chamber, the responding member is allowed to move to a position for preventing the elastic member from being bent toward the side chamber. Thus, engagement of the latch and the striker is not released in case of emergency.

[ What is claimed is:] [1.]1. A latch unit comprising:a casing having a holding chamber for holding a striker with an engaging portion, a side chamber situated adjacent to the holding chamber, and an introduction opening communicating with the holding chamber for introducing the striker into the holding chamber;a responding member movably situated in the side chamber;an elastic member situated in the casing to separate the holding chamber and the side chamber and projecting toward the introduction opening from an inner portion of the holding chamber, said elastic member having a base portion fixed to the casing and an engaging projection protruding inwardly of the holding chamber, said engaging projection, when the engaging portion of the striker is fully inserted into the holding chamber, being located in the holding chamber at a side of the introduction opening relative to the engaging portion of the striker to thereby prevent the engaging portion of the striker from being extracted from the holding chamber; andan urging device situated in the side chamber for urging the responding member to a side of the base portion of the elastic member and having an urging force such that when a force is applied to the striker for urging the engaging portion of the striker to disengage from the engaging projection, the responding member is moved at a side near the engaging projection to prevent the striker from disengaging from the latch unit.
