For this reason, it is possible to prevent the latch striker 110 from becoming thick due to the sum of the thickness of the coil spring 130 and the thickness of the tension plate 128. As a result, the latch striker 110 can be reduced in size.

  Further, in the latch striker 110 of the present embodiment, a pair of convex portions 128A and 128B are formed at point-symmetrical positions around the axis line 124A of the striker main body 124 in the outer peripheral portion of the tension plate 128. When the tension plate 128 is rotated by the urging force of the coil spring 130, the upper convex portion 128A slides on the upper inner wall 138B of the storage portion 138 of the mounting base 126, and the lower convex portion 128B It slides with the lower inner wall 138C of the storage portion 138 of the mounting base 126. For this reason, the sliding resistance between the tension plate 128 and the mounting base 126 is reduced. As a result, the tension plate 128 rotates smoothly, and centering is possible even when the biasing force of the coil spring 130 is small.

  Further, in the latch striker 110 of the present embodiment, as shown in FIG. 12, the pin 141 provided on the engaging protrusion 142 of the striker main body 124 engages with the groove 139 of the storage portion 138 of the mounting base 126. . For this reason, the assembly of the latch striker 110 is easy. In addition, the striker body 124, the tension plate 128, and the coil spring 130 can be held on the mounting base 126 by this engagement, so that the assembly of the latch striker 110 is further facilitated.
