Is stationary. In addition, the hook member is pivotally connected to the opening of the casing on the upper side, and when an earthquake occurs, the hook member is in contact with the contacted portion only when the pendulum-like member swings and tilts, The lower side of the hook member can protrude outward from the casing opening. Further, the hook member has a structure in which the upper end is pivotally connected to the opening of the casing so as to be swingable on a vertical plane substantially orthogonal to the swinging direction of the pendulum-like member. The pendulum-like member and the hook member can be accommodated in the casing, and an extremely compact structure can be obtained.

  Then, the hook member locking portion is mounted on the furniture body side, and the drawer side is only mounted with a stopper body that can lock the hook member according to the present invention. And can be prevented from falling off. This device has a small number of parts, is extremely simple in construction, can be provided at a low price, and can be easily mounted on the furniture body and drawer. And the operation | movement which prevents the drawer | drawing-out and dropping-out from the furniture main body at the time of an earthquake occurrence is performed reliably.

  Next, according to the invention of claim 2, the pendulum-like member is pivotally connected to the inside of the opening of the casing from the position of the center of gravity, so that the line connecting the center of oscillation and the position of the center of gravity is normally connected. Is stationary so that is in the vertical direction. Further, the hook member is pivotally connected to the opening of the casing at the upper side than the position of the abutted portion, and the protruding portion is more than the back side of the hook member only when the pendulum member is tilted. It is set as the structure contact | abutted to a to-be-contacted part.

  For this reason, the contacted portion is pushed outward from the opening by the protrusion of the pendulum-like member, and the hook member is located at the lower part of the hook member with the pivot connection point with the casing as the center of rotation. The side can reliably protrude outward from the opening of the casing. Then, the hook member locking portion is mounted on the furniture body side, and the drawer side is only mounted with a stopper body that can lock the hook member according to the present invention. And can be prevented from falling off. The other effects are the same as those of the first aspect.

  According to a third aspect of the present invention, the abutted portion is formed in a substantially horizontal shape on the upper portion of the hook member, and the operating projection portion is arranged at an appropriate interval at the upper end of the pendulum-like member. The hook member is normally formed so that the abutted portion is positioned between the two operating projections so that the pendulum-like member can be tilted in either the left or right direction. The hook member can be actuated. Therefore, the seismic latch according to the present invention can be mounted without being restrained in the pull-out direction of the drawer due to the shaking at the time of the earthquake.

  Next, the invention according to claim 4 is such that when the protruding portion of the tilting pendulum member starts to contact the contacted portion due to the occurrence of an earthquake, both longitudinal ends of the contacted portion are substantially curved. Thus, the protruding portion of the pendulum-like member can start to contact the contacted portion and can be moved so that the contacted portion can be pushed away smoothly. Therefore, the hook member as well as the abutted portion can immediately react to the occurrence of an earthquake and protrude outside from the opening of the casing.
