Latch device

A latch device, comprising:

• a housing;
• a sliding body including a striking portion abutting against an engaged/disengaged member, and a cam groove, and disposed relative to the housing so as to be capable of advancing and retracting;
• a spring member urging the sliding body in a direction such that the sliding body protrudes from the housing;
• an engaging body rotatably supported relative to the sliding body, and including a claw portion on an end of the engaging body;
• and
• a pin member moving in such a way as to trace the cam groove,
• wherein the engaging body moves between a locking position wherein the claw portion is protruded to a striking portion side of the sliding body and engages with the engaged/disengaged member, and a locking release position wherein the claw portion is retracted from the striking portion side and is released from engagement with the engaged/disengaged member,
• wherein when the sliding body is pressed and the sliding body moves against an urging force of the spring member, the sliding body is retained in a position after a movement thereof through cooperation between the cam groove and the pin member, and the engaging body moves from the locking release position to the locking position,
• wherein the engaging body includes
• a front plate portion from which the claw portion extends,
• a back piece portion projecting backward from the front plate portion, and
• protruding portions formed in a middle of the engaging body and protruding from the back piece portion in a same direction as a protruding direction of the claw portion,
• wherein pivotal supporting portions, rotatably supporting the engaging body to the sliding body, are provided on the protruding portions, and
• wherein in a state in which the engaging body is positioned in the locking position,
• the striking portion of the sliding body is positioned between the claw portion and the protruding portions, and
• a line segment connecting one of the pivotal supporting portions, and the claw portion in a state where the engaging body is positioned in the locking position, approximately corresponding to an engaging/disengaging direction of the engaged/disengaged member, wherein the pivotal supporting portions from a rotational center of the engaging body, and the protruding portions and the claw portion protrude substantially perpendicular to an upper surface of the front plate portion.
