Abstract: A latch device including a pair of circuital cam grooves having different planar shapes formed in opposite surfaces of a latch body. A guide lever is inserted into the circuital cam grooves so that tips of tracing portions of the guide lever do not contact bottom surfaces of the circuital cam grooves. The circuital cam grooves have a heart-shaped projection and a triangular projection, such that torsion is generated in the tracing portions because of differences in configurations of the circuital cam grooves. A restoring force of the guide lever acting opposite the torsional force causes the tracing portions to circulate in a given direction. As a result, compared with conventional latch devices, fewer components may be used. Wear on the circuital grooves of the latch body can be prevented. When the torsional force is eliminated, the tracing portions move in a direction where the groove wall surfaces are not provided.
