BUCKLE AND SEATBELT DEVICE WITH SAME

[Object] To provide a buckle whose length in the tongue insertion direction can be further reduced. [Solution] A first ejector spring 16a is provided in a position in a buckle 7 out of an area ± of the path of movement of an engagement portion 6a of a tongue 6 and an imaginary extended area extended from the area ± in the direction of movement of the engagement portion 6a, and on the outer side (on the side opposite to a second side wall 8b) of a first side wall 8a of a base 8. A second ejector spring 16b is provided in a position out of at least one of the area ± and the imaginary extended area ², and on the outer side (on the side opposite to the first side wall 8a) of the second side wall 8b of the base 8. Therefore, a bracket 18 for fixing the buckle 7 to the vehicle body can be provided closer to a tongue insertion hole 17, and therefore the length of the buckle 7 in the tongue insertion direction can be further reduced.
