Claims

[Claim for Utility Model Registration] A cab is supported on a chassis frame so that it can tilt between a normal upright position and a forward tilted position, and a pair of strikers are fixed on the side of the chassis frame facing the lower rear end of the cab. and a cab locking device that is attached to the lower rear end of the cab and engages with the pair of strikers to restrain the cab in the upright position so that the cab cannot be tilted, the cab locking device being locked and unlocked by an operating lever. A locking mechanism on a driving side and a locking mechanism on a driven side that is interlocked with the locking mechanism on the driving side via a connecting rod to perform locking and unlocking operations, and the locking mechanism on the driving side and the locking mechanism on the driven side are connected to the striker. Each of the latch members includes a latch member that is pivotably pivoted between an engagement position in which the striker is engaged and a disengagement position in which the striker is disengaged from the striker, and is biased in a direction to swing from the engagement position to the disengagement position. , the locking mechanism on the driving side has a restraining position in which the latch member is restrained in the engagement position so as not to be able to swing;
The locking plate has a driving locking plate that is swingably pivoted to a restraint release position for releasing the restraint of the latch member and is rockably operated by the operating lever, and the driven side locking mechanism is configured to release the restraint of the latch member. a restraining position in which the engaging position is restrained so as not to be able to swing;
A driven locking plate is pivotably supported to a restraint release position for releasing the restraint of the latch member, and the driving locking plate swings between the driving locking plate and the driven locking plate. The cab lock device is characterized in that the driven locking plate is connected via the connecting rod so that the angle at which the driven locking plate swings is greater than the angle at which the driven locking plate swings.
