Claims (1)

[Scope of claim for utility model registration] (1) A center pillar is hinged to the side of a loading platform, and the center pillar is set in either an upright position where it stands up against the loading platform or an overturned position where it falls to the side of the loading platform. At the same time, an engaging element that can move up and down is provided on the side of the loading platform, and the engaging element set at the raised end position is engaged with the middle pillar in the upright position to hold the middle pillar in the upright position, A doorway support device for a truck that supports a doorway in an upright position with the center pillar integrated with the center pillar held in an upright position includes a support member provided on the side of the loading platform and a support shaft provided on the support member. an operating lever which is pin-coupled to, has one end as an operating part and the other end as a connecting part with the engaging element, and moves the engaging element up and down by swinging between an upper operating end position and a lower operating end position; , a protruding locking piece portion provided on the support member, which raises the engager to the upper end position and locks it to the operating lever at the upper operating end position, and prevents the engager from lowering; and the support member; A tilting support device for a freight vehicle, characterized by comprising a resilient body provided around a support shaft between operating levers, and constantly projecting the operating lever in a direction in which it can be locked with a locking piece. (2) In paragraph 1 of the claims for utility model registration,
A tilting support device for a truck, in which a locking piece provided on a support member and a mutually locking portion of an operating lever are each provided with a locking means for preventing the operating lever from separating from the locking piece. . (3) In paragraph 1 of the claims for utility model registration,
The locking piece of the support member is formed to protrude toward the surface on which the operating lever swings, and the locking piece guides the operating lever in sliding contact between the upper operating end position and the lower operating end position. The support member is formed with a holding portion recessed in a step shape relative to the end surface formed on the locking piece so as to hold the operating lever at the lower operating end position, and A tilting support device for a freight vehicle, in which at least a portion of an end surface formed on the holding portion side is a sloped guide surface that slopes upward from the holding portion.
