摘要 PROBLEM TO BE SOLVED: To hold an engine cover in a door opening state by operation of only one hand, and to ensure a large opening angle in the door opening state. SOLUTION: A guide hole 28 made from a long linear guide portion 28A and a V-shaped guide 28B is provided on a stay guide 27 of a door opening holding mechanism 21. A first bending portion 28B1 of the V-shaped guide portion 28B is formed so as to curve along a moving track 25 when a tip end side of a stay 22 rises and falls at a position on an opposite side to the linear guide portion 28A. A second bending portion 28B2 is formed from an end portion of the first bending portion 28B1 to have a shape which is generally bent in a V-shape, and extends outward in a diameter direction of the moving track 25 in regard to the first bending portion 28B1. When the engine cover 14 is held in the door opening state, the tip end side of the stay 22 is hooked to the second bending portion 28B2 to be locked. COPYRIGHT: (C)2007,JPO&INPIT
