Abstract

A hydraulic circuit includes: a locking cylinder (22) capable of elongating and contracting to switch between a fixed state in which a bucket is fixed to a front loader and a released state in which fixing of the bucket to the front loader is canceled; a first locking oil passage (141) through which the hydraulic oil to be fed to the locking cylinder (22) flows to put the locking cylinder into the fixed state; a second locking oil passage (142) through which the hydraulic oil to be fed to the locking cylinder (22) flows to put the locking cylinder into the released state; and a connecting oil passage (160) that connects the first locking oil passage and the second locking oil passage, and has a throttle portion (161) capable of adjusting the flow rate of the hydraulic oil flowing between the first locking oil passage (141) and the second locking oil passage (142).
