PROBLEM TO BE SOLVED: To prevent damage and fall off of the expansion plug for a line pressure detecting hole provided on the lower part of a transmission case. SOLUTION: A line pressure detecting hole is opened on a swollen portion 11 connected to an oil pan mounting flange surface 10 and an expansion plug 15 is screwed into the detecting hole. A common bracket 20 retaining an oil cooler tube 27 is fixed to the oil pan mounting flange surface 10 by an oil pan mounting bolt 19 together with the oil pan. A flat portion 23 of the common bracket 20 is extended for enough to completely cover up the swollen portion 11 and covers up the expansion plug 15 from the road side. The number of parts items do not increase because the common bracket 20 is commonly used for retaining pipings and covering up the expansion plug 15 which is prevented from being damaged and becoming loose by being protected from rocks on the road. The expansion plug 15 may not fall off should it become loose by setting the gap between the expansion plug 15 and the flat portion 23 in a smaller dimension than the screwing length of the expansion plug 15. |
