Claims

[Scope of utility model registration request]

A shovel arm 4, which has a shovel 6 at its tip that can be freely swung up and down, is installed on the traveling machine body 3 so that it can be raised and lowered, and can be operated in the vertical direction through a hole b formed in an upwardly inclined surface a at the front of the engine cover 14. Accordingly, the shovel working device operating lever 16 is protruded to raise and lower the shovel arm 4, and to swing the shovel 6 up and down with respect to the shovel arm 4 in conjunction with the left and right swinging operation, and to perform a neutral operation of the operating lever 16. Arm lowering operation position D from position N
The locking device 17, which prevents the engine cover from moving downwards, is attached to the engine cover 14 so as to be swingable up and down between an active position in which it is swung upward and is leaning against the upwardly inclined surface a, and an inactive position in which it is swung downward. This is a lock structure for an operating lever of an attached shovel loader, and the locking tool 17 is dimensioned so as to come into contact with the operating lever 16 at a neutral operating position as the locking tool 17 swings from the working position to the non-working position. a tilt lock portion 20 that prevents the operating lever 16 from swinging from the neutral operating position to the shovel downward swinging operating side;
A lock structure for an operating lever of a shovel loader provided in the locking tool 17.
