Abstract: A readily attaching-detaching structure of a front loader that can make the attaching and detaching work to a vehicle body easier, a front loader, and a work vehicle. The attaching-detaching structure of a front loader is provided with a first retained member that is on either a main frame on a vehicle body or a sub-frame that supports a boom; a second retained member on the other of the main frame or the sub-frame; a first retaining member that retains the first retained member and is on the side opposite of the first retained member; a second retaining member that retains the second retained member and is on the side opposite to the second retained member; a first guiding member that guides the first retained member to the first retaining member when the sub-frame is mounted on the main frame; and a second guiding member that guides the second retained member to the second retaining member when the sub-frame is mounted on the main frame.

Abstract: An attaching-detaching structure of a front loader that can make the attaching and detaching work to a vehicle body easier, a front loader, and a work vehicle. The attaching-detaching structure of a front loader is provided with a thumb which, on a sub-frame that supports a boom, is supported so as to be able to move between an engagement position for engaging with a main frame provided on a vehicle body and a release position at which engagement with the main frame is released, and which is biased in the release direction toward the release position from the engagement position; and a lock bar which, on the sub-frame, is supported so as to be able to move between a regulated position for regulating movement of the thumb in the release direction from the engagement position, and a regulation release position that allows the thumb to move to the release position.

Abstract: A front loader includes a working tool and an attachment body to which the working tool is attached, including a lock pin configured to attach and fix the working tool, a lock lever configured to move the lock pin between a releasing position and an attaching position, and a latching portion having a retaining mechanism configured to retain the lock lever at the releasing position and another mechanism configured to move the lock lever to the attaching position.

Abstract: A stand of a front loader includes: a main body that is disposed on a boom and swings between a supporting position in which the main body supports a front loader and a storage position in which the main body is stored; a grounding-member swing shaft that is disposed on the main body and engages with the boom to hold the main body in the storage position; a swinging member swingably disposed on the boom; and an engagement lever disposed on the swinging member, wherein the main body has a guiding hole that guides the engagement lever to regulate a swinging range of the main body.
