Description of the Invention ([Technical Field to which the Invention belongs] The present invention relates to the improvement of the latching device. When the coupling state is made, the coupling portion of the coupling body protrudes from the moving part, and The coupling part is used for restraining the object to be restrained from being moved in isolation with respect to the restraining object, and when the state is released, the combining part is retracted and housed inside the moving part. As such a conventional technique, for example, it is disclosed in Japanese Patent Publication No. 7_40061. That is, when the conventional technique is pushed into the depth of a casing (box), the conventional technique is provided in the system of the movable element. On the one hand, the engaging portion of the combined body protrudes downward, and on the other hand, when the moving member protrudes from the opening portion of the casing, the engaging portion forming the integrated body is accommodated backward and accommodated inside the moving member. There is a compression spring between the casing and the moving member. At the same time, a device for specifying the position of a moving part formed by a combination of sliding engagement protrusions and a cam is provided. The compression spring is for pushing the moving part in a direction that often protrudes against the housing. Positioning is based on the push-in operation of the moving parts of the housing, so that the sliding engagement protrusions and cams are properly restrained from disengaging, the moving parts are made into protruding positions protruding from the openings of the housing, and pushed into the end of the housing The function is to switch between positions. The shell is installed on the box body that is opened and closed by the door leaf. On the one hand, a door stop (Striker) is installed on the inside of the door leaf corresponding to the position of the shell. When the door is closed when the member is in the protruding position, the moving member is pushed into the housing by the door and stopped at the pushing position according to the position regulation device.

V. Description of the invention (2) The door stop of the lintel can keep the lintel closed. On the other hand, when the lintel is pushed from the above state to the closing direction, the moving member is returned to the original protruding position by the function of the position regulation device, and the lintel moves in the opening direction. At that time, the coupling part of the coupling body was accommodated backwards inside the moving part, and the coupling state with the door stop was released, and the lintel could be opened immediately after the formation. According to this conventional technique, when the door is opened, the moving member is usually in a protruding position, and the coupling portion forming the coupling body is accommodated in the moving member backwards. Therefore, it is possible to prevent the joint portion of the joint body from being damaged by contact with other objects, and at the same time, it does not damage the appearance. [Problems to be Solved by the Invention] However, in the above-mentioned conventional technology, the moving body is rotatably supported by the coupling body, and the rear end of the coupling body is located in the guide groove of the casing. The position of the moving guide groove is changed, and it is used to move the rear end of the coupling body up and down, so that the coupling portion is made by the moving part. That is, the state where the rear end of the combined body is often in contact with the guide groove of the casing is that the position of the combined portion cannot be changed except with the movement of the moving member. Therefore, the combined portion of the latch device and the door stop of the door are engaged. In the state, when an excessive external force is applied to the direction in which the lintel is opened, the external force will directly act on the latch device or the door stop, which may cause damage such as damage to the joint. In order to prevent such a situation, it can be considered that the coupling body is composed of a material that is easily elastically deformed. That is, due to the elastic deformation of the ensemble to absorb this paper size, the Chinese National Standard (CNS) A4 specification (210 X 297 mm) applies 312375 (Please read the precautions on the back before filling this page)
