The arcuate grooves 26a and the radial grooves 26b can be formed by press molding, in which case the embossed portions 26c are made to protrude by the amount that the grooves are indented.

Similarly, as shown in FIG.
A grease reservoir portion 26 is also formed therein.

The auxiliary latch member 4 is placed on one side of the support member 30.
0 is pivotally mounted via a pivot 41, and the hood 1
2 is formed with a striker portion 14 to which an auxiliary latch member 40 engages and disengages.

The auxiliary latch member 40 is biased counterclockwise in FIG. 2 by a biasing spring 42, and is normally in contact with a stopper 36 fixed to the support member 30. The auxiliary latch member 40 has an engaging arm 43 extending upward, and an engaging claw 44 is provided at the tip of the engaging arm 43. The engaging claw 44 has a striker portion 1 of the hood 12.
A guide inclined surface 44a is formed on which the guide plate 4 abuts. An operating arm 45 extends from the base of the auxiliary latch member 40, and a handle 4 is provided at the end of the operating arm 45.
