Oil Path Structure

An oil path structure, comprising:

• a first member having a joint surface, and having a first oil path opened to said joint surface formed therein;
• a second member having a second oil path formed therein and joined to said joint surface such that said first oil path and said second oil path communicate with each other;
• an annular sealing member sealing between said first oil path and said second oil path;
• and
• an oil amount adjusting member limiting an amount of oil flowing through an oil path;
• wherein
• said second member has an accommodating portion formed at a position adjacent to said joint surface and on route of said second oil path,
• in said accommodating portion, said annular sealing member (in contact with said joint surface and said oil amount adjusting member positioned on a side of said annular sealing member opposite to said joint surface are arranged,
• said oil amount adjusting member is sandwiched between said annular sealing member and a wall surface of said second member defining said accommodating portion, and
• a plane including a surface at which said first member and said second member abut each other and said wall surface at which said oil amount adjusting member and said second member abut each other are opposed to each other.
