A folding-in-half foldable cart, comprising a bottom frame (6), a front frame (2), a rear frame (3), a left side frame (4) and a right side frame (5). During folding, the middle portion of the bottom frame (6) is pulled upwards so as to enable a front frame portion (11) and a rear frame portion (12) to be folded with respect to each other, a left engaging structure (21) moves upwards from the lower end along a left guide structure (20), a right engaging structure (24) moves upwards from the lower end along a right guide structure (23), and the front frame (2) and the rear frame (3) move toward each other to drive parallelogram mechanisms of the left side frame (4) and the right side frame (5) to move toward each other synchronously so as to lift middle supports, such that the front frame (2), the rear frame (3), the left side frame (4), the right side frame (5), the front frame portion (11) and the rear frame portion (12) move toward each other and finally form a folded state, wherein the front frame portion (11), the rear frame portion (12) and connection bases may form a U-shaped storage space (16) having a downward opening. The folding-in-half foldable cart facilitates size reduction while allowing the capacity to be maximized as much as possible.

The purpose of the present invention is to achieve size reduction.　This noise filter (A) comprises: a cylindrical bobbin (11) in which flange parts (22) are formed at both ends in an axis (S) direction; a magnetic body (27) accommodated in the bobbin (11); and a coil (28) wound around the outer periphery of the bobbin (11). The bobbin (11) is made from a synthetic resin. Since the bobbin (11) is made from a synthetic resin having a high degree of freedom in molding, the thickness dimension of each flange part (22) in the axis (S) direction can be kept small. As a result, it is possible to achieve size reduction in the axis (S) direction.

Provided are a buckle that can achieve size reduction while keeping costs low, and a seat belt device including the buckle. A buckle 10 includes: a base 11; a latch member 12 having a claw portion 12d that engages with a tongue; a slider lock member 14 for preventing movement of the latch member 12 in a latch release direction when the tongue and the latch member 12 are latched; a slider spring 17 compressed between the slider lock member 14 and the latch member 12; an ejector 15 for detaching the tongue; and an ejector spring for biasing the ejector 15 in a direction of detaching the tongue. The ejector spring has an ejector spring 18a and an ejector spring 18b arranged in parallel at the center in the transverse direction of the base 11.
